Drill or cut a 1" notch/half hole in the middle of each end, and slide into place. Secure with the U-shaped clamps in your link, and voila.
But some of the boats I've looked at don't have a ladder. If I'm going to have to make/install something anyway, why not go with something like this? I agree about having to put a backing plate - a large piece of starboard should work. Of course, I'll need access to that area of the transom, but assuming that's available, are there any other down-sides?
One idea that struck me was that, if I was in rougher water, the force of the water on the swim platform might be significantly more than the force of my fairly substantial butt on that same platform. So, I'll need to make sure the transom is properly reinforced. A swim platform would also limit my ability to add an outboard on a proper outboard bracket, should one become desirable for some reason. But, if it's done properly, the platform could also serve as an emergency mounting bracket for an outboard.
So, what else am I missing?
By the way, I'm not entirely convinced that this is really what I want to do, just soliciting opinions.
Many sailboats with rear ladders also have a gate in the back so you dont have to go over the rail.
If you construct this Just make sure you have a way to get onto the platform which drops in the water as Faster said. Its hard to lift up or put you foot on your platform out of the water, especially with the stern bobbing up and down. Thats why the bootom two rungs of most ladders are under water out of the water
Another thing you could do is put a shoe and have a side ladder.
