gpg is a PKI, or better said, it's a client to be used with an PKI (the
OpenPGP PKI, Web of Trust, or however you call it)

You probably mean the X.509 PKI. OpenPGP and X.509 are incompatible, but
I'd suggest you to use OpenPGP, as it's more secure.

Depending on whether you mean X.509 you could use gpgsm, which is also
part of GnuPG.

gpg/gpg2 -> OpenPGP
gpgsm -> X.509
