Yes, Competition Pro make a pad for CD32 (the only 3rd party one I know of - also known as Honey Bee).
They have them on www.liksang.com
but were out of stock last time I checked.
The second Q just means you can plug a standard Amiga stick in, but you only get the one button function, not 7 like the CD32. You can also use some Sega pads (SMS only?) and get 2-3 buttons.
