With FLTK it's possible to have a raw widget and use the X drawing functions to draw
into it.
Should you pick FLTK I can provide you with sample code (that is how I did it).
GTK does have drawing widgets, but you shouldn't use the X drawing functions, but the
gdk abstractions of them. But that isn't really a disadvantage, gdk provides
abstractions
for all X drawing commands (at least I haven't found one that isn't supported by gdk),
and that makes it possible to port gdk/gtk to widely different graphics subsystems,
such as Win32 (which already exists), or possibly a PDA, where one probably does not
want to run X because of the memory footprint. I have example code for that too,
and so does www.gtk.org.
I don't know about QT or other toolkits.
