These buttons along the left side will, among other things, fire off SQL
queries or start the process of asking what sort of toppings the customer
wants on a pizza.  Using GtkNotebook as you suggest would be okay for
static displays, but not this.

I see two ideal solutions:

1) Explicitly state that a widget should be put in container foo's nth
slot.

2) Have a container return a reference of some sort to the widget
contained in slot n, erasing what might have previously been there.

Can either of these be done?  How?
