Sorry, I'm still not sure what you are trying to accomplish.

Lets not worry about the implementation stuff just yet. 

When you said "PGP encrypt stuff", can you explain exactly what you are trying 
to do? In particular, are you trying to use PGP to authenticate a TLS 
connection (as described in RFC5081 - 
http://www.rfc-editor.org/rfc/rfc5081.txt) or are you trying to encrypt a 
file (as described in RFC4880, Section 3.1)?

GPGME is designed to support mail user agents handled PGP encryped/signed 
messages. Use of it for something wildly different is going to be messy.

I can't help you with a better suggestion unless you can explain what you are 
trying to do. Are you trying to generate the keys yourself, or do you already 
have them? How are you planning on transferring the private key? Are you 
trying to back-up, or transfer a file? More detail please.
