You definitely should be using OpenGL for this ... simple, clean API, 
cross platform, and well supported in hardware acceleration.  If you 
prefer "C" and only need support for X, gtkglarea is the widget for you. 
 If you need C++ and/or support for X and Win32, try the SDPGTK library 
(yes, it's a shameless plug).
