@jackjack,
Yep. So I guess that answers all this. Its not possible to create a public key without some form of computer.
I was only talking about hashes though, you could follow this post:
Well only the public key needs to be hashed to create an address. You can safely type the public key into a computer to obtain an address.
All you need to do by hand is obtain a private key and derive the public key, NOT calculate the hash.
If you are REALLY motivated you can do it in a few days I think
