That's exactly what I was was thinking.  I figured the plugin approach
would allow appender designers to provide a nice UI for their appenders,
and then a generic one would cover us.  I would intend on providing nice
UI plugins for all of the appenders shipped with log4j.

Shouldn't be any problem since the gui builder code is all mine, and it
hasn't been released publicly yet.

I initially tried to use beanutils for the project, and to some extent
it worked well.  I just found after 3 or 4 refactorings that the stuff
that was bundled with Java was much better suited to what I was trying
to do.  I can look at it again for this project.  I understand wanting
to make this available for old versions of java.
