Beginner iOS Game Design Help?

I am 15 and have been researching different ways to make iOS games. I know there are many types of coding, like Objective-C, C++, lua, and java. I have looked into softwares, but don't know which ones are best for beginners. Corona 3D looks good, it's just that I have an iBook G4 with 10.4.11 and can't run that. What are some good programs for beginners?
