Yes.  There are several open source projects (e.g., OR mappers)
which have tools that provide you with this capability.  One
which comes to mind is objectstyle.org's Cayenne Modeler.
You might want to study their code to see if you can enhance
what you already have accomplished.  (It's always good to see
how other folks approach a problem.)
