import pygtk
import gtk

IMAGE_FILE = "/put/an/imagename here"

class MainWindow(gtk.Window):
    def __init__(self, debug = None):
        gtk.Window.__init__(self)
        self.connect("delete-event", self.on_delete_event)

        btn = gtk.Button()
        img = gtk.Image()
        img.set_from_file(IMAGE_FILE)
        btn.set_image(img)

        self.add(btn)
        self.show_all()

    def on_delete_event(self, win, data):
        gtk.main_quit()

    def run(self):
        gtk.mainloop()

def main():
    w = MainWindow()
    w.run()
    return 0

if __name__ == '__main__':
    main()
