How about a simple vb program for your pretty automated simple needs that could make it easy for the user linked to a database as in something like ms access?
They have an online version, and also iPhone/iPad/iPod & Android versions, but don't know how good those are, besides, I think the online version needs a yearly subscription.
Some options if you still want to use it in your Mac: 1-Install Windows in a separate partition 2-Install Windows in a VM 3-Try the application in Wine/Crossover; both the Game and Comic collectorz apps have Platinum/Silver rate in Wine's App DB (which means most if not everything works): http://appdb.winehq.org/objectManager.php?sClass=version&iId=5494 http://appdb.winehq.org/objectManager.php?sClass=version&iId=19801 http://appdb.winehq.org/objectManager.php?sClass=version&iId=22633 Though I assume these are not options you'll be looking at...
RFGen is by far the best option in my opinion. Once you learn how to use the tools, you'll realize that there is a vast database, complete with variants and the ability to contribute yourself.
