Has this idea been brought up before? This seems like it could be a nice (optional) helper for beginners like me: Click on a note position, see some orientation info.
M&N are reversed 
otherwise, cool idea for any pc keyboard beginner!
The notes being physically positioned in practically the same way on both types of keyboards not helpful enough? Maybe not for everyone.
Surely some people are that lost, especially if they are not keyboard players. But, much more easily implemented as a printable reference card, maybe? Would probably more handy that way, too, I think.
