I cannot generally stand the way GTK, and gobject and stuff work, so I mostly have avoided them. QT is maybe a bit better, but I'm just not interested in the way it looks.

Motif has the right aesthetic, but it's hard for me to program, especially off other people's code.

I like FLTK, but the fact that it has complexities for certain types of callbacks and no native C bindings is annoying to me.

I had someone say I should just try straight XCB or Xlib, I gave up quickly with both.

I've not tried Xforms, FOX or other toolkits out there.  kinda looking for the following:

1, the ability to use the library easily with C99

2. A relatively simple look that's not too "pretty" and doesn't go for lots of extra bits

3. Decently portable, flexible and somewhat maintained?

What fits this best? I have hit the point I can read GUI code from Motif and FLTK and some dialects of GTK to some degree, but I haven't specialized.

Also, if you're suggesting Motif, I'd REALLY appreciate materials on more advanced topics, especially programming exercises.
