Well, that would be something, but...

1. It's pretty much useless. How much of a lazybones can you be to use a program instead of placing some random tiles by yourself? Just spend a few more seconds placing random tiles, your hand won't hurt, trust me.

2. I highly doubt that someone is going to do this. It's most likely insanely hard to do such a thing or maybe even impossible because different tilesets have different tile placement.
