You'll be able to use the same X-based toolkit with both X and GL applications.
Remember, the popups, pulldowns, radio knobs, and other crap all are created as
subwindows, not as part of the current window.  What you won't be able to do
is to blend (or logicop, or z-buffer, or texture map) a popup, pulldown, radio
knob, or other crap INTO a GL scene.
