Depends on how experienced you are. If you haven't done much engine work, then it could be pretty difficult.
The water pump on the 3.5L is located in the center of the engine. To get to it, you've got to remove the front stuctural crossmember, radiators, pulleys, front engine cover, and who knows what else. I elected to have mine replaced rather than do it myself -- had the water pump replaced, power steering pump replaced, new timing belt put on, new belts, and necessary fluids for a little less than $900.
You can see the water pump here (below the bolt the guy is loosening):
