Is there a mod/program wich can enable me to make custom made items?

I find myself always ending up with 2 handed sword, throwing axes, bows.

I want to make a dual long sword figher/mage/thief, but i think its there is no choise other than casomyr wich is a 2 handed wep xD

Is there a program/mod wich enables me to make myself some pair of custom made long swords, bows and amulet forexample? I would like an amulet of power wich also adds 1-2 more spells each lvl :P
