Since it will mostly be Windows, does it need to be a Windows service?  Or 
even involve Qt at all?  Why not create a Task Scheduler entry to monitor the 
desktop application at intervals (say 10 seconds), and restart it when it 
stops?(hint: This is one of the ways that Microsoft keeps its automatic update 
system service running constantly under Windows 10) Instead of a Windows 
service, you could simply make the Qt program a stand-alone console app that 
the Task Scheduler launches to perform the monitoring.

I would imagine other platforms (OS X, Linux) have similar scheduling mechanisms.
