Low-level graphics

I want to learn how to create graphical interfaces for my programs. I know nothing about the subject. If possible I'd like to learn how to write my own GUI generator rather than use some prebaked toolkit. Eventually I'd like to do some 3D.

If anyone knows of any decent resources on these subjects, please post them here. Thanks.

Are you drunk? I think I get what you're trying to say but your prose is horrendous.
Anyway, if I understand your post correctly, the culprits are, as always, bloated frameworks and inefficient context switching.
