Help for new (young) developers

[popblanks]

Hey Toucharcade people!! My friend and I wish to create a game during the summer. The problem is that we barely have any experience with programming, and barely have any supplies(I will be getting a macbook air during the summer. Wait. Should i get the macbook air or another laptop?I don't have that much money though). Also, we're both only 13. So basically we're like 2 noobs trying to achieve an impossible dream.
So my question to you guys is what programs, computer languages should we learn(to create the game)? I will be creating the music(I am familiar with all types of instruments. Have been playing violin for 9 years and mom is a piano teacher) and my friend the art(No skill...). What programs should we use for both of them? We understand the hard work ahead of us but are willing to try it. If this succeeds we can get into a good college and create even better games.
