The BusyCal folks have reported that having a contact solution was a pretty popular feature request. But they are currently focusing on bug fixes and additional features to BusyCal to bring it up to par (printing being one of those missing features).

They did say that once development for BusyCal slows down, they'll turn their target sights on to other things (hopefully a contact solution).

I don't think they have plans for a Windows version. They are laser-focusing on the Mac platform and probably would need a lot more help to expand into the Windows world if they decide to go that route.
