There are a few applications out now that may be able to help you out. 1Password and LastPass are both password vault or lockers. They allow you to save passwords for applications and websites. That way you have a single password you use to keep the vault/locker secure and then all of your other passwords are stored for you so you don't have to write them down or try to remember them all.
