[PyQt] how to make a simple client/server app using TCP to communicate ?

[Strato]

Hi there,

I am searching how I can build a simple client/server application, that 
use a TCP port to communicate.

I've searched in the PyQt API but I wasn't able to see some kind of 
class that permits me to make my application to bind to a TCP port, 
waiting for incoming messages.

My goal is only to send some simple, plain-text messages, no XML or HTTP 
or HTML or particular protocol is required for this to work.

I've seen some methods that permits to send some stuff in HTTP but 
nothing that is to "receive" HTTP requests.

I suppose I missed something, so can anybody points me in the right 
direction ?

Thanks,
