When using glade, the pointer that is returned to you from glade_xml_new():
http://developer.gnome.org/doc/API/2.0/libglade/GladeXML.html#glade-xml-new

is the topmost hierarchical widget, hence, if the pointer is the first
window, you can not then find the second window using this pointer.

The way to do this is:

        GladeXML *xml1 = NULL;
        GladeXML *xml2 = NULL;
        GtkWidget *window1 = NULL;
        GtkWidget *window2 = NULL;

        /* this shows the window - unless it is invisible */
        xml1 = glade_xml_new ("myinterface.glade", "window1", NULL);

        /* this gets the widget pointer for window 1 */
        window1 = glade_xml_get_widget (xml1, "window1");

        /* connect signals here */

        /* clean up */
        if(xml1) g_object_unref(G_OBJECT(xml1));

        /* get window 2 */
        xml2 = glade_xml_new ("myinterface.glade", "window2", NULL);

        /* this gets the widget pointer for window 2*/
        window1 = glade_xml_get_widget (xml2, "window2");

        /* connect signals here */

        /* clean up */
        if(xml2) g_object_unref(G_OBJECT(xml2));

It does work.  Perhaps you have missed something?
