Sorry, I was sleeping during the first part of this thread, so I'm
probably missing some of the requirements for what you're looking for. But
is this where you'd go like

     cat $* | xmessage -file -

in bash? In a script, this should work whether you give a filename on the
command line or just let it read stdin. (It'll actually concatenate any
number of named files, obviously.)
