You have three options:

1) Use a separate thread, and communicate with the main thread with a
GAsyncQueue, and continue to do drawing in the main thread.

2) Initialise the glib/gdk thread systems before calling gtk_init(), do
your processing in another thread, and surround calls to gtk/gdk with
gdk_threads_enter() and gdk_threads_leave()

3) Keep it the way you have now, but do:
while(gtk_events_pending())
    gtk_main_iteration();
every now and then to process events and redraw windows as needed.

The API docs and tutorials will be helpful in the former two cases.
