graphics library to make widgets

[hannes]

Hi guys,

I've made some programs with qt and wxxidgets so far, and i got the idea
of making my own widgets with some kind of graphics library like SDL(this is rather good, but it supports only one window in 1.2).

Are there some good libraries to make my own widgets in?

EDIT: This is just for making widgets, not 3D game design.
