There is many ways to accomplish this, here goes...

Here is the URL of some graphics algorithms :
http://math.berkeley.edu/~jlevenbe/grafalgo.html
Maybe you can find some of it there.

Also, you may want to visit The Numerical Recipes homepage :
http://www.nr.com/
You will surely need a good random number generator. The C's srand()
and rand() may just not good enough (read the Random Number section on
this homepage to find out why).

I've also got a .html that describes the Diamond-Square algorithm. I
just don't remember where I got it. Can mail it to your private e-mail
if you want.

Last, you can try to find the homepage of FREECIV, a free civilization
game on a search engine (don't remember the URL). This game uses
random terrain generation. You can download the sources (in C), or you
can ask the programmer via e-mail.

PS: I've also have written some test programs using Diamond-Square,
Fault Cosine and Snow algorithms. Just tell me if you want the sources
(in C, compiled with DJGPP), but it's rather messed up.
