If I understand your question, no, there is no secure viewer built
into GnuPG.  There are many reasons, but two good ones are that GnuPG
is a command line application, and you can't really make a secure
viewer on the command line, and by its nature a secure viewer would
not be nearly portable enough.

However, GnuPG can call other programs to do other tasks (keyserver
access programs, JPEG viewers for photo IDs), so it's not impossible
that GnuPG could call an external secure viewer program.  I don't know
of one offhand though.
