Symmetric Encryption Requirement

We have a need for either 

1) GNUPG needs to be able to Symmetricly encrypt a file with 
triple DES and write the key used to a separate file (in clear text) 
and the encrypted data to a different file.

2) Strip out the encrypted key from an PGP/GNUPG encrypted file
and write this key to a different file in clear text.

Reason, we have files sent to us that have been encrypted by PGP
using symmetric encryption and we want to be able to decrypt the
data using mainframe(S/390) based triple DES decryption.

The mainframe doesn't know anything about encrypted keys protected
by a pass phrase, it just wants the encrypted data and the key used
to encrypt the file.

Thanks for your assistance.

What are the facts? Again and again and again --- 
what are the facts? Shun wishful thinking, ignore 
divine revelation, forget what "the stars foretell", 
avoid opinion, Care not what the neighbors think, 
never mind the unguessable "verdict of history" --- 
what are the facts, and to how many decimal places? 
You pilot always in to an unknown future; facts are
your only chance. Get the facts!
