Or just be sure that you provide a no-argument public constructor to your
subclass of JDialog to appease the designer(in addition to making the class
public). Your code does not have to use it, but the Designer will. If you
want, you can put code in the no-argument constuctor so that it throws an
exception if  it is ever called outside of the designer.

if (!java.beans.Beans.isDesignTime())
           throw new RuntimeException("Do no use this constuctor");

 to make sure that it is never used in real life.
