I downloaded the NBCog.exe and was able to execute the 'NBWin32Window
getFocus setWindowText: 'Hello using Native Boost' example you showed
above. It looks me to like they are direct calls to the Windows API
which don't require any external DLLs other the built in Windows
ones..

However on Linux would that mean it may be necessary to use different
code for Gnome or KDE/Qt for instance, or use some other native or
crossplatform widgetset like Wx?
