Well, there isn't any *real* documentation on the subject, so you
might have to go source code hunting.  The two data structures you want to
look at are GtkDrawingArea and GdkPixmap (or GdkImage) GtkDrawingArea is a
blank canvas on which to create anything you want, and you can find out
how to get it going.  You'll need to know about how to use gdk_draw_*
functions, which are defined in gdk.h

Pixmaps and GC's are defined in gdktypes.h.  gdk_draw_* functions, and GC
functions are defined in the file (GTK-INSTALL-DIR)/include/gdk/gdk.h

Hope this helps!
