Not within GPG.  GPG stores keys within keyrings.  Passphrases are  
stored outside the system (but see the gpg-agent for a local  
passphrase cache).

Not using GPG, but there are several tools available for split keys on  
the net.  For example: http://point-at-infinity.org/ssss/

That is not GPG.  That is a completely different implementation of the  
OpenPGP standard.  You should ask on the Bouncy Castle forums.
