No maps needed and it wouldn't be used for Stumbling so Wifi wouldn't come into it.

So what you really need is a database that will store a Long/Lat waypoint from serial input on a user command and continuously compare that to the current position.
Most GPS units, even the oldest and cheapest (w/o mapping) do exactly this. They functions are in hardware, and are designed to this very well. Rather than going to an PPC application, you'd be better off just buying a GPS off eBay. I'd suggest an Garmin Etrex or the Magellan 315.
