Here's a step by step way of doing this. I'm assuming you already have GlovePIE, and if you have PPJoy you can't install it yet. First, since you're running a 64 bit OS, you'll need to enable testsigning, which you can do by opening the command prompt (type "cmd" in the start menu's search box) and inputting "bcdedit -set testsigning on" and then rebooting. After doing so, you can install PPJoy. Ignore windows' warnings about unsigned drivers. Once it's installed, it'll automatically open the configuration utility. It should already have a virtual joystick in the menu (if it doesn't, click "Add" and then again in the window that appears); select it, click "Mapping..." and follow these instructions:
-On the first screen select "modify the mapping for this controller"
-On the second screen give the controller 6 Axes, 16 Buttons and 1 POV hat, and assign the first 3 axes to the X Y and Z axes respectively with axes 4-6 assigned to the X Y and Z rotations respectively
-On the third screen assign the axes and rotations to analogs 0-5 in order descending through the menu (x axis=analog 0, y axis=analog 1, etc)
-The 4th screen is similar to the third; assign the buttons to the digital inputs in order (button 1=digital 0, etc)
-Same for the last screen; assign digitals 16-19 in order to the pov hat directions and click "finish" and "done"
Now, grab this GlovePIE script:

Connect your Wii Remote with Classic Controller attached to your PC and select "Run" in GlovePIE while the lights on the remote are still flashing. It should now only have one light on. Finally, open Dolphin and its CGpad config, select "DInput/0/PPJoy Virtual Joystick 1" as the device and configure it as you wish. All inputs but the home button should be recognized and able to be mapped.
Also, you've probably noticed the annoying watermark that appeared on the desktop after you enabled testsigning. Here's a way to get rid of it, while keeping testsigning on:
