//Get the content view of the window
//By default the conten view is an NSView object
NSView *view = [window contentView];
//Then add your buttons
[view addSubview: buttonOne];
[view addSubview: buttonTwo];
[buttonOne release];
[buttonTwo release];

  [box stTitlePosition: NSNoTitle];

The openapp tool is needed if you use the gnutep layout. But by
default gnustep use the FHS layout, so you don't need the openapp
