IMHO the best way to handle the passphrase in a GUI program is by
using Quintuple-Agent.  The problem is that this software has no
direct support for GnuPG (it uses a wrapper).  I am working on
extending it to speak the GnuPG agent protocol directly, but although
that most code exists it is not yet ready.  I need at least 1 spare
day to complete my changes.

What you can do for easier migration is to check whether a variable
GPG_AGENT_INFO exists and if so, pass the option --use-agent to GnuPG.
