Rich,

The Netbeans GUI builder won't load forms if they're not JavaBeans.  I 
don't think it'll load any class that has arguments in the constructor, 
or if it instantiates class variables in the constructor.  At least, you 
have to be careful what happens in the constructor of a form.  Try 
commenting out everything but the generated initComponent() method in 
your constructor, remove all the arguments if there are any, and try 
loading the form again.
