Jack,
A long time ago I wrote a patchwork landscape demo in the code archives - you may want to take a look at that. The random landscape is created by extruding heights based on cos/sin functions within a specified radius.
However, for a much better effect you want to look at bezier patches. With these you can get a nice undulating landscape using relatively few control points.
I have done this successfully but only interpolate on the Y axis. I kept the x/z step values uniform for simlicity. E-mail me if you want to see some code.
