Probably an integration of sockets with the main loop to allow for 
asynchroneous communication.
Qt has a socket class that will deliver events when data is received or 
transmitted. It's a long time that I had a look at this, but I think 
it's available from PyQt as well.
Alternatively, I have successfully used Quamash, which is an integration 
of the Qt event loop with asyncio.

For new projects, I would always recommend to use asyncio as this is 
available in the standard library.

For wxPython there is some code to integrate with asyncio, but I have 
never used this myself.

Alternatively, the communication can always be placed into a separate 
thread, posting events to the main application / frontend.
