If I create an application using Cocoa and Xcode on my Mac, can I also generate a windows exe from the same code? i.e. Is cross platform development feasible in this environment? I use Mac at home, but work is Windows only. I have a couple of windows app I wrote for XP and have to rewrite and I would love to do it on my mac and cross compile. One is a time management utility for shift workers, the other is a specialised utility to check satellite parameters and calculate various factors.
