Seems like Java would be the better option for you then.
Not only because you are already familiar with it, and it's always good to stick with the language you're familiar with, but also because Java allows for better publishing options, you don't just get PC/Mac as possible platforms, you can make your game to run on the web and Android, and that's just a huge perk.
I don't have much Java experience myself, so I can't really help you in that area, but I hear that Eclipse is the best you can get as an IDE for Java.
Thanks. I'm sticking with java and am going to follow the new bostons tutorial so I learn functions and whatnot, and I have seen some other tutorials and one is specifically for making a game. and ive always used eclipse
