The example code I put on my first name was created by Glade.
So if I understand correctly, I just need to put
GtkWidget * button = gtk_button_new ();
gtk_widget_set_name (button, "button");
gtk_widget_show (button);
gtk_object_set_data_full (GTK_OBJECT (window), "button", button, (GtkDestroyNotify) gtk_widget_unref);
gtk_container_add (GTK_CONTAINER (window), button);

No! That isn't correct. When you create a window it has a ref count of
1, but that count is owned by GTK. You can't call unref(), you must
call gtk_object_destroy(), which will cause GTK to drop its count. If
you can unref() then GTK will segfault eventually.
In the example code I think gtk_object_destroy() on the window will
free everything, though I don't understand why the extra ref on the
child button is used, since containers ref their children anyway.
