That looks OK, but you can just use this:

  gtk_signal_connect (GTK_OBJECT (ok), "pressed",
                      GTK_SIGNAL_FUNC (on_ok_pressed),
                      &contain);

This is the problem. It should be


void
on_ok_pressed                          (GtkButton       *button,
                                        struct _contain *contain)
{
 printf ("%s", gtk_entry_get_text(GTK_ENTRY(contain->port)));
}
