X11 is a client-server system.  In this case, GraphicsMagick is the 
client.  You need to have an X11 server running somewhere.  This could 
be a computer that normally comes with X11 (e.g. Linux) or it could be 
be added to Windows.  For example, Cygwin comes with an X11 server. 
Once you have the X11 server started, you need to make sure that 
the DISPLAY environment variable is set appropriately (or use GM's 
-display option to specify the display to use).  Some X11 
servers require some additional authentication.
