There's a DFB port of wx, although I'm not sure how much attention
it's received lately. I know it's been actually used for at least one
application. Gtk can also run directly on a framebuffer - that's what
openmoko does, for example.

Sounds like a full scale widget toolkit is quite a bit heavier than
