Edward
I was thinking of getting the G2 cause it seems pretty awesome, but I heard its not a D-SLR, I'm not very Camera-savy so can anybody tell me the difference? and if anybody has got one, would you recommend it?

Hi Edward,
The main difference between the Lumix G2 and a DSLR is that the G2 does not have an optical viewing system. Other compatible cameras in this class include the Olympus Pen E-P1, E-P2 and E-PL1 plus all the Panasonic Micro Four Thirds models. (See Link below). Similar cameras in this class but using an even newer proprietary lens mount are the Sony Nex-3 and Nex-5 (Second link). Most of my points in this answer will address the Olympus/Panasonic models as they have collaborated on these designs while Sony is pursuing their own development path. Other than lens mount most of the points would apply to the Sony designs as well. NOTE: The Sony design uses a somewhat larger sensor which has some advantages but may eventually limit how small their cameras can be.

The big advantage to this relatively new class of cameras is that they can be much smaller, lighter and can take advantage of a number of simpler and more affordable lens designs.
The most significant drawback to the Electronic View Finder used is that there may be a slight delay in seeing what is actually occurring in front of the camera, other limitations are that it depends on more electronic processing so it consumes more power. It also user a different lens mounting system (Micro Four Thirds) so there are relatively few lenses available that take full advantage of the cameras features.
The processing delay (known as "shutter lag") is a common limitation with many point and shoot cameras and is one of the notable advantages of SLR and DSLR cameras which have nearly instantaneous response to a shutter press (except when in "Live View" mode). The lag is a result of two things ~ 1] the processing time required to convert the image from light to an electronic signal and write it to the display screen and 2] the time it takes the camera to lock focus and exposure before releasing the shutter after the shutter button is pressed.
The power consumption issue is addressed by improved circuit design, more powerful & efficient batteries and more sophisticated software for power management.
The lens mount issue is mitigated by two main factors ~ 1] Micro Four Thirds is an extension of the Four Thirds lens system and can accommodate (via an optional adapter) all of the 4/3 lenses made by Olympus, Panasonic and Sigma. 2] Micro 4/3 and 4/3 are very flexible mounting systems and can also accommodate thousands of older 35mm lenses In fully manual mode.
Digital SLR cameras use an optical viewing system that operates at the speed of light, for all practical purposes instantaneous imaging, except when switched into "Live View" mode where the image is displayed on the EVF. This design, by its nature requires a mirror plus a porro-prism or porro-mirro to orient the image in an optical viewfinder, the mirror flips up out of the optical path when the shutter release is pressed and, usually, returns to position after the shutter closes. This causes the camera to "blink" during the exposure. The advantages to this are extremely fast reaction times, fast and accurate focusing, very flexible systems and the ability to make extremely robust designs. The main disadvantage is that the mirror mechanism requires a deeper camera body. This limits some lens designs, particularly for extreme wide angle lenses which have to be constructed as a sort of "backwards telephoto" to stay out of the mirror's operating area.
Many experienced users and professional photographers are very skeptical of the development of the new class of cameras but I would point out most professionals were very reluctant to move to digital 10~15 years ago but the vast majority have since either switched to or, at least added, digital photography to their capabilities.
HTH. Feel free to email me if you have any other questions.

I just purchased the canon g11 should I return it for the Panasonic g2 or any other camera? Sony h2 old camera?

Who knows?
The cameras are usually bought for specific use, and each particular model will fit some set of applications. Unfortunately you didn't tell us why you bought g11, and what makes you have second thoughts...
But in general, and not knowing why you went for g11 in the first place - my generic advice would be to return it and get Nikon D3000 with 18-55mm lens. You will get a lot more of a camera than any of the listed in your question for about the same money g11 costs.
The D3000 is a real full featured SLR camera. It has all the features g11 has, plus flexibility of interchangeable lenses and true through the lens viewfinder. It's sensor is much bigger than that on g11, giving it a lot better overall picture quality, especially in poor light, and it's bigger body makes it much easier to hold stable in your hands. It does not have live view, which you will really not need that much once you get a hang on the excellent optical viewfinder, and will probably not fit in a purse or small handbag. These are about the only down sides.
The g11 is an excellent p&s camera, but it's just a bit too good for general consumer to pay the price. The serious amateurs and sometimes professionals can shed out its price tag for just one feature - a convenience of it being more compact than an SLR. Other than that, a real SLR will be far far better.
Good luck,
LEM.
