Simple Fortress is just a slightly tweaked world generator and embark that allows your dwarves to carry far more supplies initially.
Also the starting abilities of your dwarves have been selected to some useful professions.
This is designed to give you plenty of time (A couple years) to learn the ropes and how to handle your fortress without the initial pressures that are usually placed on a fortress.
With food and drink taken care of, with simple weapons and armors already supplied, and with plenty of raw materials you can take your time and learn how the intricate industries of dwarf fortress interact.
http://dffd.wimbli.com/file.php?id=3802Just download and unzip into your dwarf fortress directory.
Then Generate a new world using "Simple Fortress" World preset. (It increases the embark points and also makes the world a bit less extreme)
Then When you play choose "Simple fortress" As the embark profile and you will have a large amount of goods per-selected that should make your initial years far less hectic.
