modifiable dialog button labels?

[Roger Davis <rbd soest hawaii edu>]

Hi all,

I am trying to code some reusable GtkDialogs (i.e., create them only once,
then hide and reuse them later as necessary rather than destroying and 
recreating every time). I need numerous dialogs which ask a simple question
and then have two buttons for the user to choose between, e.g.,

        Favorite drink? Wine/Beer
        Which way? North/South

(Poor examples maybe, but you get the idea.) Seems like a waste to create
a bunch of different dialogs that are all using the same basic structure,
I would prefer to just create one and then modify its elements as needed.

I can see how to change a text label inserted into the dialog's content area
to alter my question text, but so far have discovered no way to alter the
text labels used in the buttons which I supply at creation time to
gtk_dialog_new_with_buttons(). Seems like this ought to be an easy thing
to do, but I can see no way to retrieve any pointer to the dialog's button
objects nor any way to explicitly set their labels after the dialog
has been created. Any ideas?  

Thanks!
