NCH Software HourGuard

I'd like to request NCH Software's HourGuard to be made into a portable app.
Program: HourGuard Timesheet Recorder
Site: http://www.nchsoftware.com/timesheet/index.html
Lic: http://www.nch.com.au/general/legal.html#104

Or if you know an open source timesheet thing like this, could that be made instead?
