I'm no expert on Customize. The code in wid-edit+.el might help
(http://www.emacswiki.org/emacs/wid-edit%2b.el), or it might not - dunno. 

If not, I believe that Lennart has some widget code that might help. And of
course you can look in the Lisp sources that come with Emacs. And there's the
widget Info manual, FWIW.

If you do write some useful widget/Customize code, please share it (e.g.
gnu-emacs-sources@gnu.org or Emacs Wiki).
