Same as the existing CLI tools - it would start an RT thread that polls
on the RTC, then tell the user to generate some load (switch windows, do
a find /, pingflood the default gateway, whatever), then report back the
maximum latency.

I'd like to, this is why I said the GUI should be separate from the back
end.

I don't have the bandwidth to do the whole thing - I need someone (or a
few people) to make a mockup GUI and then I'll wire up the buttons.
