Below is what came out of my copy of ProMash. There are any number of convenient online recipe calculators; you don't really need standalone software, especially at your stage of the game. There's the HBD Recipator, TastyBrew, and others.
Your beer looks yummy. I think I'll have to brew one of these; my pipeline is getting rather low.
