Programming Eclipse plugins in Jython?

[Kenneth McDonald]

Is it easy or difficult to implement Eclipse plugins in Jython? And  
if the former, are there any starter's guides you could recommend?

The desire is an editor plugin for a syntactically very simple  
proprietary language. I'd like to have paren checking, syntax  
colorization and (to start with at least) a few other small features.  
Unfortunately, there's quite a hump in learning the Eclipse API well  
enough to do even simple things (or at least that's what my reading  
seems to indicate), and I was wondering if I can cheat and use Jython  
to simplify the process.

Thanks,
Ken
