MusE also has a framework for creating custom Qt UI:s for LADSPA
plugins. This means you can create a gui in Qt-designer, f.ex. name it
1050.ui (1050 == Freeverb), and put it in MusE's shared plugin
directory, which is checked on startup. If there's no 1050.ui-file there
when you launch the Freeverb plugin, it goes for a standard gui,
otherwise the custom one is initialized. 

You simply give all input widgets in the gui, that manipulate a LADSPA
parameter, a name starting with "P", and set the id-property of the
widget to the parameter index of the plugin. The connection is done
automagically and there's no need to recompile the app. In fact, you
don't even need to write any code yourself to create a custom LADSPA
gui.
