Haha, I'm trying to build the same thing, only in form fillable pdf form. Or rather, I've asked my girlfriend to do it, since she's fermiliar with pdf creation. :p
My end goal is a little more direct though. After playing my first few sessions, I've realized I want more GM centric resources - forms for me to fill out to create a campaign, or at least an individual story. My thinking is if I generate a mini-charactor sheet for each NPC, location and major event, I'll have a good skeleton for the game - enough to keep the world solid, three dimensional and the story structured, while giving me the flexibility to have the world adept to PC reactions and my own improvisations. We'll see how it works out I suppose.
