how to i get the arrow-buttons moving?

[Gary Kline <kline thought org>]

here are thee labels that show up when you use the gcc compile string.
how do I get the up- and -down arrows to point at the label and echo the
"label strings"?

#include <stdio.h>
#include <gtk/gtk.h>

                     GtkShadowType shadow_type)

  GtkWidget *button;
  GtkWidget *arrow;

  button = gtk_button_new ();
  arrow = gtk_arrow_new (arrow_type, shadow_type);

  gtk_container_add (GTK_CONTAINER (button), arrow);

  gtk_widget_show (button);
  gtk_widget_show (arrow);

  return (button);
}

static void
button_clicked (__attribute__ ((unused)) GtkButton *button,
                gpointer   user_data)
