I have some program ideas that I would like to build for PC, Mac, and Linux/Unix.
The process I have in mind is to write the core libraries in C++, then program each UI based on OS.
Mac: Objective-C and Cocoa
Linux/Unix: C++ and GNome/Gtk
But, I only have a PC (Windows Vista). So, is there a way to program for the Mac (and *nix) on a PC?
Thank you for your time,
