You don't necessarily need to pull out perl. Try this from the shell: 
name_of_cmd <<END
answer_to_question_1
answer_to_question_2
answer_to_question_3
answer_to_question_4
END

This works if you know the answers ahead of time. If you need to make decisions based on the output of the program, then Expect.pm is your baby.
