GPGsm does not do anything with GPG keys directly. The Keys it creates
are stored inside GPGsm and are derived from GPG keys, AFAIU.
For your purpose you have to use the GPGme library.

GPGme does what you are trying to do, without prompting, except for
cases where PIN or password are required. This events are handled by
GPGsm is for managing X.509 certificates. I'm not sure if it can handle
moved keys. It should, if it interaqcts with gpg-agent. That's
something I'm not really sure of.
