A simpler programmatic way is gtk_widget_modify_base.

You can change the style direct over the style interface. The
function gtk_widget_modify_style() should do the trick:
http://www.gtk.org/api/2.6/gtk/GtkWidget.html#gtk-widget-modify-style
http://www.gtk.org/api/2.6/gtk/gtk-Resource-Files.html
http://www.gtk.org/api/2.6/gtk/GtkStyle.html
The style change should apply immediately AFAIK.
Cheers,
Andy
