I am starting a new thread as the other thread is about systemd shims.

I will start using Lazarus for the GUI and then start the C++ backend
which will run with root privileges thanks to sudo configured to only
run the backend.

For anyone's information, this is how it will be:

Main Window:
ESSIDs listbox plus these buttons: Add, Edit, Delete, Start and Stop.

Dialog:
ESSID edit box and password edit box with Save, Save & Connect and
Discard buttons.

Thanks.
