There are a few tools available here:
* Dungeon Turn Tracker
* Die Roller
* PC Generator
* Wandering Monster Encounter Generator
* Dungeon Stocker
The results are about as random as random gets, so you probably will need to make some tweaks on the fly. For example, the 1st room in a 1st level dungeon I generated had a single Dwarf in it and something like 16,000 gold pieces as treasure.
The website has been around since a year ago last July and I for one liked looking at the change log to see what has been teased out of the site since it went live. All these tools were coded by Tony Bravo
