I think Rick is right - you do need to build a GUI. I use the
batch file technique to launch IDL GUI-based programs, but
getting 'print' output to go to a DOS command window is not
possible, I believe.

I was thinking you were just using hello world printing as a
simple test case to figure out how to launch IDL programs in
a manner that is transparent to the user: double-click an
icon just like any Windows program.
