Why dont you simply make a new gtk.Dialog and pack your Entry's into its
vbox. For example:

dialog = gtk.Dialog(None, None, gtk.DIALOG_MODAL)
dialog.set_title("GTK Entry")

entry1 = gtk.Entry()
entry2 = gtk.Entry()

entry1.connect("focus-in-event", on_focus_in)
entry2.connect("focus-in-event", on_focus_in)

dialog.vbox.pack_start(entry1)
dialog.vbox.pack_start(entry2)

dialog.run()
dialog.destroy()
