Create a (or modify your existing) class to be a subclass of 
NSWindowController. The change your constructor to look like this:

- (id)init
{
   if (self = [super initWithWindowNibName: @"YourWindowName"])
   {
       // do normal stuff that you'd normally do in init
   }
   return self;
}

Then in Interface Builder, drag this class in, and change the "File's 
Owner" custom class to your NSWindowController subclass. Set File's 
Owner's window outlet to be the window. Make sure you don't have any 
instances of the class instantiated in IB. All of your connections 
will now have to hook to File's Owner, not any instantiated version.

Finally, in the code that you want to bring up these many windows 
(for the sake of this message, I'll just say there's a NSButton with 
this action method connected to it), use this code:

- (IBAction)openNewWindow: (id)sender
{
   YourNSWindowControllerSubclass  *wc = 
[[YourNSWindowControllerSubclass alloc] init];
   [wc showWindow: self];
}
