How add email field to anonymous user's comment?

I want to give a permission to anonymous users to comment, however the default form does not include user’s email. Can I manage, without contributed module, to create a comment form which user have to leave their email/name and notify me per each comment, as well? If need to install contributed module, please advise which of them (a link) – I found following topic but do not know what exact modules suitable to my requirements? Comment notify or Comment Admin Notify or Simple Comment eMail Notification or other one?
