Re: Do you think the Raspberry ft is powerful enough to do this at the same time?

Well running Wine is impossible, as its i386 only and the Pi is an ARM based board.  Wine (as the acronym says) is not an emulator, just an API which looks like the Windows API.

Not a problem, linux exports gpio pins as files under /sys/class/gpio, you can open them using normal file IO from Java and away you go.

Re: PWM as a voltage regulator

Much the easiest and cheapest way to get 5V from a 12V battery is a car USB adapter.  They are so common now, especially as all new phones (except iPhones) now use them for recharging.
