I've never set up submenus, but menus without a menu bar are easy.
Use something like this:

static void
menu_popup(GtkWidget *widget, GdkEvent *event, Chart_app_t *app)
{
  static GtkWidget *menu;

  if (menu == NULL)
    {
      GtkWidget *menu_item;

      menu = gtk_menu_new();

      menu_item = gtk_menu_item_new_with_label(_("Help"));
      gtk_menu_append(GTK_MENU(menu), menu_item);
      gtk_signal_connect_object(GTK_OBJECT(menu_item),
	"activate", GTK_SIGNAL_FUNC(on_help_menu), GTK_OBJECT(widget));

      /* Repeat as required to set up all menu entries.  Use
       * gtk_menu_append(GTK_MENU(menu), gtk_menu_item_new());
       * to create empty "seperator bar" menu entries. */

      gtk_widget_show_all(menu);
    }

  gtk_menu_popup(GTK_MENU(menu), NULL, NULL, NULL, NULL, 
    ((GdkEventButton*)event)->button, ((GdkEventButton*)event)->time);
}

Setting up submenus should be a simple matter of repeating this
pattern to create menu popup routines for the nested submenus, and
attaching these submenu routines to the "activate" signal of their
parent menu items.
