You should realize that on UNIX, at least, this is pretty much the
standard way to implement another program's capabilities.  Programs such
as mutt which 'seem' to have integrated GnuPG do fork/exec calls.  Note
that GnuPG has a rich set of communication handles to use, and a
well-structured option-parsing mechanism, so you aren't missing out on

As far as I know, the GPL does not allow this.  You should read the GPL
yourself for clarification.  However, you simply call GnuPG through
fork/exec calls, you can use this technique in non-GPL software.  Also
note that the FSF, which holds the copyright for GnuPG, seeks to have more
stuff under the GPL than the LGPL:
