Difficulty of making Space Invaders in GTK+?

Question

What are the difficulties of making Space Invaders using GTK+ (latest stable) in C?

I did it once in high school with Visual Basic so I figured it wouldn't be that hard with GTK, but now I'm confused on even where to get started?

Can someone point me in the right directly, perhaps like how to put 1 alien on the screen and have it go back and forth?

Answer 1

Here is a short introduction to game programming on X-Windows with the GTK+ toolkit. I hope this will get you started rendering the figures on the screen.
