They are two tools sharing the principles of public-key encryption.
PGP was implemented first. Sadly being non-free, many people considered
it not usable for security tasks.
Thus, a Free Software implementation was started, that's GnuPG.
Further, a standard [1] was drafted so other tools could be created
which share the same principles. Or maybe this is nonsense and someone
can correct me. ;)

Should be answered above. :)
