Yes, no doubt!

Well,

First, you need to init the threads, at the begin of your program:

    gtk.gdk.threads_init()
    gtk.gdk.threads_enter()

and call:

    gtk.gdk.threads_leave()

at the end (not really needed).

Then, use a serializer. I attached mine. When you need to call a GUI
stuff from your thread, use:

    ret = serializer.apply(<func>, <param1>, <param2>...)

This will push the <func> on a queue (note that you can wait for a return
value if needed). To have the queue executed, you need to call:

    gobject.timeout_add(50, serializer.processWork)

before the gtk main loop. So, the serializer queue will be checked every
50 ms (try different values depending of your config).

Hope this helps.
