Well, I can't help you with a tutorial at this point, as I am still doing babysteps in C2, but read a lot of the pcg wikia (recomended above), and check out roguebasin (http://roguebasin.roguelikedevelopment.org)for articles and algorithms on random dungeon generation.
There are also tutorials on dungeon generation for both C2 and CC on this forum. Alas, it is late and I am sleepy, but I will attach the links soon.
Saying that, I would love to see a .capx on how to approach this type of random dungeon generation in C2.
