I've seen dongles you can buy (I think in the $30-$50 range) that sit between your normal non-QMK keyboard and your computer. Then when you press a key, the dongle takes the keycodes from your keyboard, runs them through QMK, and everything works like your keyboard had QMK to begin with.

This is probably the route I'd go for a wireless board. I'd likely choose a keyboard that really has the wireless part down (Logitech is a decent option here, I think - the experience with their receiver is better than Bluetooth for input devices in my experience) and then run it through one of those dongles if I really wanted wireless.
