If you are using it for a facebook game and WoW is in the background, Blizzard wouldn't be able to detect it seeing as WoW would be in the background (almost all, if not all, programs that simulate clicks can only click the button for the program in the foreground, not the background).
There's have numerous reports of players being banned due to using macros and autoclick programs to simulate actions (just look up WoW and Logitech keyboards, the G-keys).
In terms of programs, yes there's free programs out there, some aren't as easy to use, but they are out there.
