No, unfortunately it is not free. I was just throwing it out there if you had an old copy of the game.
I played around with MapTools a little last night and it looked like it'd be fairly easy to work with provided you had art assets to use as tokens and background objects. It seems to come with enough of each to demo the application but not much else. It seemed rather obtuse to me at the start but the online tutorials helped a lot (at least the ones I got to).
