Glade provides a lookup_widget() function to get a pointer to any widget
in the same window. So you could use:


 void
 on_ok_button1_clicked                  (GtkButton       *button,
                                         gpointer         user_data)
 {
  GtkWidget *entry1, *entry2;

  entry1 = lookup_widget (GTK_WIDGET (button), "entry1");
  entry2 = lookup_widget (GTK_WIDGET (button), "entry2");
  ...

assuming your widgets are named "entry1" and "entry2".
