Cha, you certainly have quite a way to go, but after all no one is born a programmer, so there's no reason you can't do it.

I suggest you do yourself three favours :

1) start with Python, as many have suggested. It's good for beginners, but not a toy language in any way : it'll grow with you and not hobble you as you mature. Above all, it'll teach you early on what clean and readable code means. Learn with simple stuff before you tackle GUI apps so you don't hit a wall right on.

2) When you do however, skip the world of pain that is GTK and go straight ahead with Qt. It's available on N8x0 now, it's the future for Maemo, and there are great tools like QtDesigner and eric4 that you can use on almost any desktop.

3) if you follow 1) and 2) you can save time and despair by buying this book :

Good luck !
