See, the problem is the fundamental abstractions in GUI programming are
radically different. GUI programming in Unix for example is
_dramatically_ different from Windows. One needs to worry about things
like server side pixmaps instead of client side pixmaps and some of the
modern widget kits (like Gtk+) have a complex OO design.
Not to mention the fundamental difference between message-based GUIs
(like Win32) verses callback based GUIs (like X) verses signal/slot
based libraries (like Qt).
It's not impossible, but it's very very difficult.
