Try running rubyw.exe instead of ruby.exe. 
( But I don't have this module, because my nmake do not make it :((   )

# 
# 
# I'm writing a small program under Windows using the Ruby and 
# GTK+ mingw32 ports.  I wrote a small C executable to wrap and 
# this program.  The problem is when I run the program it also 
# opens up an empty Windows console.  Is there a way to prevent 
# this, or at least to hide the console?  Be aware I'm a 
# beginning coder and very unfamiliar with Windows programming.
