Thank you all for the answers but think I didn't really clarify what I meant so that's my fault.
What I mean is a generator for the wallet address and private key. So more just a website hat will generate paper wallets.
So creates a wallet address then the private key so then won't need to install any wallet software until I wish to claim the wallet.
as i said above you can still use the official wallets to do that. you just install them offline, then generate a new wallet and then export your key pairs. after that you can do with the keys whatever you like. print them on a piece of paper and that is your paper wallet.
this is actually what i suggest you to do, it is much safer.
if you don't like it then take a look at this site: https://walletgenerator.net/
it is like the bitaddress.org for altcoins
Awesome thanks a lot for your help and website provided.
