Implementing standard library sockets [SOLVED]

Hello everyone, and sorry in advance if the answer to this is obvious.
It might be worth mentioning that I'm using PyQt4, although answers can be given as if I were using C++, since translating that to a Python solution should be trivial.
I have a chat server that was not written with Qt in mind, so of course it uses standard library sockets. I would like to create a simple client without having the complexities of threads. In other words, I would like something that essentially works just like QTcpSocket, using the readyRead() signal.
Any ideas??

edit:
Wasn't aware that QTcpSocket was compatible with standard UNIX sockets. Everything works as expected.

Sockets are sockets. This is something your system handles and not Qt.
