If your happy to use a two hop circuit as explained in the article I believe that you can use the same control port technique with the tor installation for windows (don't use the valida bundle as I am under the impression that the control port is passworded with a random password so that the valida control panel can interface with tor).
Saying that, if you want to change the source and recompile under windows I found this guide, not sure how useful it is as I am currently at work and can't test it. http://gitweb.torproject.org/tor.git?a=blo...gw-creation.txt
Try it out, hope this helps.
