Haven't done precisely what you're suggesting. I've talked directly to
Xlib for the rendering of this one program, since then I've pasted on a
front-end via GTK+v2. Took some doing, but the old direct Xlib interface
still works. Depending on precisely what you're doing, you might want to
use OpenGL functionality instead.

I like GTK+/GDK. They provide a very nice interface. If you need OpenGL's
functionality there are two libraries, GtkGLArea and GtkGLExt. Appears
the former is better known, while I suspect the latter is better
designed.
