Hi - from the code below, I suspect that you are trying to order your
window front in your main function, before the application is made active
... which won't work - you can't order front any window before the
application is 'launched'.

You probably want to create an application delegate, and move the code to
order front the window into applicationDidFinishLaunching:.

I wrote a tutorial about it once,

http://www.gnustep.it/nicola/Tutorials/WindowsAndButtons/

it should explain how to create a simple window and ordering it front
correctly, including full working source code and explanation of the
start-up sequence.

Hope this helps.
