grabbing a spinbutton from a dialog

[Rob Benton <rob benton conwaycorp net>]

I know there's probably a better way to do this than what I'm 
attempting.  I have a New menuitem that I want to create a dialog with 2 
spinbuttons.  On the response handler the function needs to extract the 
values from the 2 spinbuttons.  Here's my flow:

Mainmenu->New->create a dialog with 2 spin buttons->signal connect
response->get dialog vbox->get first hbox->get spinbutton->get value
                                      +->get second hbox->get 
spinbutton->get value

So far I've been trying to use the gtk_container_get_children() 
methods.  Is there a better way to do this?  That seems like a lot of 
code to get 2 ints.
