That would be awesome!  There are a few obstacles though.  Chiefly,  
all of the actual GUI code needs to be in a single thread, and that  
shouldn't be the ChucK VM/audio thread because the GUI code could  
cause the audio to skip.  So each GUI function call needs to go  
through a thread safe message passing interface between the VM thread  
and GUI thread, which make writing the wrapper a bit more difficult.

One interesting idea would be to use OSC to communicate between ChucK  
and an external Python/Java/etc. agent, but wrap the OSC code on the  
ChucK end in user friendly convenience classes.  For example, the end  
user would write something like MySlider.setValue(), but that  
function would just be sending the appropriate OSC messages behind  
the scenes.  This could be written entirely in ChucK and Python/etc.,  
without requiring a custom chuck.  The user would only be seeing  
ChucK code, and the OSC would be completely transparent.
