It wouldn't necessarily be opening a controlling terminal,
but you certainly can display program output by writing
to /dev/tty1, or any other /dev/tty?.
You might want to look at other ways to invoke your program
too. Cron works nicely for a program invoked at intervals,
but what you are doing sounds more like something that would
be run continuously. It could either be run as a daemon
process started at boot up via a one of the rc scripts,
or probably best of all as a process started by init from
the /etc/inittab file.
