It's not that hard. I do it occasionally at my shop.
One thing to remember is get a piece of thin (1/4" or so) foam to lay over the seat after you cut it and put the gel pad in. The 1/4" foam gets rid of any lines you'd see from the foam/gel being there after you stretch the cover over.
The last one I did was a gel pad off Ebay, a memory foam pillow from Walmart, and a piece of 1/4" regular foam from the local fabric shop. Recessed the gel pad into the seat, put about 3/8-1/2" of memory foam on top of that, and then the 1/4" foam over the whole seat.
-an electric knife to cut the memory foam
-spray adhesive to keep everything in place
-stapler (I use a cheap Harbor Freight air powered one that works ok but not great)
