Yes, but you will need a way to connect those guitars to my adapter...
If the Wii one is a Rock Band Guitar, it will require a the original dongle. If it is a Guitar Hero Guitar, it will require either a Raphnet Wii Adapter, or my own nunchuck adapter ( https://rolllimitless.com/nunchuck-guitar-adapter/ ) (in addition to the normal guitar adapter).
The Xbox 360 one will require a 360 to USB Dongle. Official Microsoft ones will work out of the box. Official ones are hard to find, but 3rd party ones work too, I just might need to make a new firmware for a 3rd party one (all the 3rd party ones have different drivers). Here's a link to a 3rd party one (https://www.amazon.com/Mcbazel-Wireless-Receiver-Microsoft-Xbox-360/dp/B076GZFLR3)
You'll need a 360 to PC adapter like this to connect wireless 360 controllers to the computer.
so i did a quick amazon search, is this the kind of thing i would need?
Wireless 360 guitars work with both the Guitar Adapter and the rb4.app method (on Windows) as long as you have a 360 to USB dongle (like https://www.amazon.com/Mcbazel-Wireless-Receiver-Microsoft-Xbox-360/dp/B076GZFLR3/ref=asc_df_B076GZFLR3/)
if you get a 360 guitar you will need a Microsoft adapter https://www.amazon.com/Mcbazel-Wireless-Receiver-Microsoft-Xbox-360/dp/B076GZFLR3/ref=sr_1_6?crid=ZT0VWOH5ZSPR&keywords=xbox+360+wireless+adapter+for+pc&qid=1640167031&sprefix=360+pc+wireless%2Caps%2C157&sr=8-6
this also lets you connect any 360 wireless controller to your pc.
