(adding answer from comments above)
Set up your Responses as a Custom Post Type. Then you can use WordPress’s native comment system for, well, comments on the Responses.
To tie the Responses to the Questions, you can simply use something like update_post_meta( $response_id, 'question_id', $question_id );. See update_post_meta() for details.
