This is the point of OpenGC, so the answer is "fairly easy", provided you
are comfortable working with C++ and OpenGL. Assuming you are using a
supported Sim (Flightgear or FS200x currently), you'd only have to write the
gauge/instrument itself. If you're using an unsupported sim or some other
data source, you'd have to write a subclass of ogcDataSource in order to
acquire data for the displays.

As a reference, I've been able to prototype relatively simple gauges and get
something working in a few hours. Obviously, the more complex your gauge is
the longer it will take to write. As a programming strategy, you should
think about breaking a gauge (instrument) down into "gauge components". For
instance, a Boeing 777 PFD contains an artificial horizon, heading
indicator, airspeed indicator, etc. It's very possible that your project
could start with some of the existing components and modify size, color, and
a few other details to achieve what you're looking for.

Incidentally, the CVS repository has recently moved, I'll be posting a
message to this list as soon as anonymous CVS is up and running. If you run
into any snags writing a gauge or have more questions, let me know.

Cheers,
