Not to sound rude, but I doubt your pc is that slow. You would have to be running like a pentium III or worse... Game Maker runs perfectly fine on my crappy netbook that is over 2 years old running off an Intel Atom n270 and an Intel gma 945 graphics accelerator.
I'm sure the Blitz products could run as well. You could also learn SDL and C++. Hell, even XNA 3.0 ran on this netbook with basic 2d operations.
I understand you are new, but you shouldn't let your hardware "issue" dictate your creative process. I can confidently say that no one will do all the work for you. The only way that would happen is if your are Miyamoto in disguise. The only way you will receive contribution from others is for you to put forth demonstrations of your game. Then, the community can help guide you in how to improve and what not. Everyone has awesome fan game ideas, but no one is going to make it for you. YOU have to take the initiative. Even if you don't succeed, you'll gain ,hopefully, valuable insight and knowledge into the world of video game design and programming.

Trust me, unless you have a computer made pre 2001, you can run Game Maker in the least. Also, here is a link to a game where the creator had very limited hardware and still made a really good game that was released in the last few years on hardware that was very dated for it's time:

Don't let this post turn you away from ZFGC, either. The community is more than happy to help you as you begin your journey into programming should you choose to start it.
