This is pretty cool stuff. I bet the same modification/idea could be
used to launch a gui designer tool as well.

You might consider, rather than launching an external application,
rather, calling into a python module/function that returns some result.

Now it might be that calling into the module launches an external
application, but the idea is that the difficulty of launching and
parsing program specific output is encapsulated into the module.

All GRC properties dialog has to know is how to call a function and
process its return values.
