The best way to do things is do some study, then post questions you have about it. There are lots of people, many of them professional game developers that visit this site. You'll find that, at first, gaming is very much an independent study kind of thing. With study groups, you need people at about the same experience level, using the same language, etc, and even then, it mostly amounts to independent study. I guess, if you do want to do that kind of thing, choose a language and a graphics library of some kind, and see if you can get a group going at the graphics library. That's also a good place to ask questions. Here, it's more general questions like game dev, general language questions, etc.
