Gamecube Controller for Wii Answered

With the Wii U coming out without any nintendo gamecube controller ports, I was wondering if it were possible to still somehow mod a gamecube controller so that it could work on a Wii U.  Since classic controllers that plug into a Wii Remote will work on a Wii U, i was curious to know whether it is possible for a gamecube controller to be modded so that it is recognized as a Classic controller.  Somehow connecting a gamecube controller to a Wii remote, since a classic controller and a gamecube controller have pretty much the same buttons.  If this is possible how would it be done?
