About a week ago, I finished the first release-quality beta version of an application I have called Chatly. It isn’t a whole lot right now as not all features have been fully implemented, but it includes both the client (a stand alone application that uses PyQt for GUI management) and a server. Both client and server utilize Twisted under the hood for robust network communications. The project itself has been written entirely in Python. I also have a brief write-up on this site about Chatly, although you might be more interested in looking at Chatly’s Trac page that includes browseable sources!

I currently have only a Windows release available for download, although you may also grab a source-only version linked from here. The distutils/setuptools setup.py doesn’t quite work yet, but I do intend to package a functioning Python egg in the future. For *nix platforms without Python (or the necessary libraries), I’ll also be releasing a “freeze” distribution. For now, you’ll need PyQt 4.4.3 or later, Python 2.5 or later, Twisted 8.2 or later, and some patience. I’d like to build an OS X package in the future but haven’t any access to Apple hardware for now. If you can help, just drop a comment here as I may have future projects that will be Qt-based.
