Yes, I've done this before.

You really need to know the GTK timeout callbacks
and how to optimize them, along with using GDK RGB
buffers for drawing output really helps.

Have your callback check for the network stats as
often as possible, and directly update the GtkDrawable
(or whereever you are drawing out to) as quickly as
possible.

Remember, optimul use of GTK timeout callbacks and
GDK RGB buffers.   If you have any specific questions
let me know.
