This is the first I try to use github hello

write a framework for gui programming split the gui part with the callback functions

I got the idea from EPICS (Experimental Physics and Industrial Control System). EPICS is transfer actions through ethernet. So I try to use gui client to send control messages, and use callback clients for response when they receive the control messages.

I'm not quite familiar with socket programming. Learn, then do.
