Is there a way to link the Wii classic controller? (GCp)

[Horrible N00B]

I will be making a GCp, like everyone, but I'm switching a few things up. One will be the controller. Could I use a Wii classic controller somehow, whether through a port or soldering something to something?

You won't get, controllers that plugs into wiimote, to work without adding a microcontroller. But there's "classic controllers" designed to work on the gamecube and Wii by plugging into the console. Search on Ebay and take a look on the controller's connector
