I also have some PHP code here, if that helps: https://gist.github.com/scintill/3549107  If you use the compressed version (shown in my code), it saves a few bytes in the blockchain when the balance in the address is spent, although not all clients can import the private key (for example, I just learned Electrum doesn't.)  If you know Javascript, the code at bitaddress.org might help too.  Casascius' utility (below) does it in C#.

When you get something working, I suggest using something like bitaddress.org or Casascius' Bitcoin Address Utility to ensure your keypairs are valid.
