Some googling would have shown you what this means.  You need to be 
running an X server and set the DISPLAY variable in order to use GTK+ 
(or any other X11 GUI).

This being a Cygwin/X question, it really belongs on the Cygwin/X list; 
redirecting accordingly.

GTKmm for Windows is just that -- for WINDOWS.  Cygwin's GTK+ is a 
*NIX/X11 version and needs a Cygwin-built GTKmm, which is available from 
Cygwin Ports.

'/usr/bin/gcc' is a symlink, which Windows itself doesn't understand. 
Cygwin commands are generally meant to be run from a Cygwin environment 
(in this case, bash, or another shell of your choice).

This is asking for problems.  You're better off keeping extra Win32 
components out of your Cygwin PATH.
