GtkWidget *label = new gtk_label_new ("CITY");
GtkVBox *vbox = new gtk_vbox_new();
gtk_box_pack_start (label, FALSE, FALSE, 0);
gtk_box_pack_start (combo, FALSE, FALSE, 0);
that's a bare minimum, you might want to take more precise control of
the sizing and spacing.

use gtk_widget_set_usize() on the entry widget inside the combo. its
ugly, and it should be easier, but it works. you might want to use
this:
