DatabaseManagerSwing Question

I am NOT a developer, so I apologize if my question is not asked
exactly correct.

I am able to administer a FOSS bug tracker called JTrac, dormant since
2008. It has an embedded Jetty app server and HSQL database. Amazingly
simple to install! On a sourceforge support page, there was an entry
about using DatabaseManagerSwing. Oddly enough, I actually was able to
follow it and get it to work. Now I can "see" the tables in JTrac and
can successfully perform SQL selects.

My QUESTION is:

Is there any HSQL specific tool, or perhaps a Swing plugin, that will
compose a "visual" display of the public tables in JTrac? (My mind is
not ready for system tables.....)

I have not been able to get 3rd party "data browsers" to work - but
that's MY fault.

Thanks.
