a graduated sphere capable of rotating

I want to simulate a cockpit instrument: an ADI(Attitude Direction Indicator) of a flight system.
The instrument has a sphere with graduations showing the heading(direction__north, south, east, west), the pitch(the angle to the ground or heaven) and …

How to texture the graduations on the sphere?

Is there an example I can use? You can send a site name where I can get useful information.
Thank you.

It is called texture mapping, you create the graduated image for you sphere in a paint program.

Then apply it to the sphere, on my website I have a example of a textures sphere and texture loading.
