Well - your JFrame sub class should have getters to give you everything
GUI related and if you just add one more super object with getters to
give you all the data model stuff, then you should be OK.

If the IDE and the program run in same JVM, then it is easy.

I am not familiar with JPDA, but I assume that if the
application is run under debugger then it is also
easy.
