OpenPGP is the standard that both PGP (a proprietary product) and GnuPG use. As they operate on the same standard keys generated in either work in both.
If you wan to send an encrypted message to someone you need to get their key. If they have told you what their Key ID is then you can pull it from a server. You then usually tell your email client that you want to encrypt the message, and select their key. Some email clients pull the key from the server automatically if you give the program the Key ID. Or you can download it from a server (http://pgp.mit.edu/) by typing in their name. Keyservers will download keys from each other so once you submit it to one, it usually gets populated around the internet after a while. I'd submit it to a popular keyserver, Ubuntu have their own which I use (http://keyserver.ubuntu.com:11371/).
