It depends how complex you want to get, and what your ultimate aim is.
Your question is really very general.

I would strongly suggest you take a look at a site like The Virtual Terrain Project.
http://vterrain.org

The subject of how to make terrains is something which you could most likely spend your entire GL career on, and indeed some people do...

Thanks for the PM, but I've generally got enough bugs and problems of my own to keep me going all day long, so I can't really just jump in and help out on other people's projects...

I really think you need to go and do some reading and perhaps choose an easier subject to cut your teeth on...

Perhaps try looking at some stuff like this..

Try using a tutorial web site like HeNE which has planety of starter tutorials on OpenGL. You can't run before you can walk...and game programming in OpenGL is no different.

Try lesson #34 - heightmap terrains as a basic intro.
