About Dialog? Can I extend it?

[Øystein Johansen <oystein gnubg org>]

Hi,

caling the gtk_show_about_dialog function gives several properties to 
set. among them I have authors, developers, translators, artists, 
documenters, etc.

However I have other names I must have in an other list with  names. A 
special thanks list of names must be displayed. And then there's a list 
of code contributors. How can I add such a page to the notebook in the 
about dialog in an easy way?

I'm using the About Dialog from GTK+ 2.6.2
