bitaddress.org is your answer

I don't believe there is an option there to use a custom private key as he asked.

Yes there is, under "wallet details"

You can enter a private key in format: WIF, WIFC, HEX, B64, B6, MINI, BIP38

For example, the private key for Base6 address "1425342302314253423023142534230231425342302314333323023142534230231425342302314 25342302314253423023" is "5JMBJfgXCPpxB5HjiVJB4YvZ2wv4M6z3wqbTjtPqFKMCEC4E2jL"

I think that is close, but given what he wrote, doesn't seem to me to be what he is asking. Maybe it is though.

I think what he wrote comes down to a brainwallet for which there is also an option under 'brain wallet'

edit:
The asociated public and private key for his "supersecretprivatekey" passphrase randomized with SHA256 are:
12f3na5TXRs4itNi9i1TCeSsXkny7A1hxp
5KHHB79dmtJHA5QfGXa5rtHdWDrx8EeiWPBaZM4o6frexXvmko6

I think that is closer to what he wants, but what he is really talking about is something like this:
