adding an Instant Messenger to evolution to offer it to openoffice

Hello

I want to request to add an instant messenger to sylpheed mail client.
there is a serverless one out here:
http://sourceforge.net/forum/forum.php?forum_id=618174

Please can you add it, so that online and offline communication meet
under one gui?

That done, we could offer it to open office as a component:

http://sourceforge.net/forum/forum.php?thread_id=1753227&forum_id=618174

Which gui language is evulution for windows using?
How long would it take to integrate the IM core into the gui of evolution?

Thanks for a short feedback.
