Thankfully there's HID to VPAD! https://github.com/Maschell/hid_to_vpad/releases (or the Wii U Plugin System by Maschell https://github.com/Maschell/WiiUPluginSystem/releases)
I've included an ini file called "GBA Smash.ini" which I have tested with Super Smash Bros. It works somewhat well.
Wii U Steps
1. Take the SD Card out of your Wii/Gamecube and plug it into your computer.
2. Add HID to VPAD to your SD Card.
3. Remove the SD Card from your computer.
4. Plug the SD Card into your Wii U.

7. Assign the GBA to a controller slot, and press the Plus/Start button on your Wii U Gamepad/Wiimote.
8. Start the game of your choosing and play with a GBA!
