You could try python, seeing as it is a scripting language. You would however need to use the interpreter which is only a small download I think.
Why not get gcc or the free borland compiler? They are free and if you want to use gcc you can find heaps of good IDEs' for them.
Or if you're running win 95/98 you would have QBasic on your computer and could learn to program BASIC.
