Take a look at FLTK (http://www.fltk.org). I've read articles in the Linux 
Journal that say that FLTK has been used in embedded devices. You can use 
FLTK for the widgets and embed SDL into FLTK for the drawing (graphs, images, 
etc.)

AFAIK, you can use nanoX as the windowing system and FLTK supports nanoX. I 
haven't used it myself though. But it might be a good place to start 
investigating?
