You can use gdk_draw_rgb_image() to draw a memory buffer to the screen.

http://library.gnome.org/devel/gdk/stable/gdk-GdkRGB.html#gdk-draw-rgb-image

Make a GtkDrawingArea and call that in expose.

You can also use cairo, though it'd probably be a little slower. If
you need more speed than gdk_draw_rgb_image() (though you should be
able to do 640 x 480 x 60 fps on most machines) you'll need to use
opengl or similar.
