how do I create an app inventory

Unfortunately, I am an app addict and I have too many apps. I love the features recently implemented to see the apps purchased. I want to be able to create an app inventory or database.

I have checked out the apps that say they are for keeping track of the apps, but they don't do what I need/want to do.

I want to:

1. keep track of the apps I have purchased;
2. keep track of the date purchased,
3. the price
4. description
5. support sites/app author
6. comments or notes for my review of the app or comments on it.

It would be nice if I could have this on my ipod touch or ipad 2, but even being able to create an Excel sheet or a database would be nice. (My laptop is a Windows 7 machine with Office 2010)

Does anyone have any ideas about how I can accomplish this without driving myself insane? So far, I have been copying the descriptions to a folder in Evernote... but I have to use the descriptions here: http://itunes.apple.com/us/genre/ios/id36?mt=8 , which I copy and paste into a note. I could put them directly into an Access database too...
