I haven't tried it myself, but rEFInd (http://www.rodsbooks.com/refind/) is a more up-to-date fork of rEFIt that seems to cover Mountain Lion. It might do the trick.

I am looking for an intuitive way to inform how to boot to Windows. I was thinking of a desktop background once they log in to the Mac side, but that doesn't seem the friendliest or quickest (though logging in to the Mac is significantly faster compared to Windows). I really don't want to tape instructions to the physical computer either.
