Don't be intimidated by the shortcuts on vassal. I've played 20 or so games, and I still use the right click and select for a lot of things, and I've never had someone have an issue with it. Vassal is great fun, is free, and is used by a lot of top level players, so you can measure yourself against the best.
Only part that I find annoying is the list building and saving, but it's necessary to make it a little taxing to save the integrity of the tabletop game.
