Building personal pages with personal login?

Hi Guys & Girls, Im very new to this wordpress format so I hope I am not wasting anyone’s time by asking the following question.

This is what I would like to do :

From my home page I would like to add a client link button which would take my clients to a page where they could then select their name which would then request their password – taking them then to their personal training page. I hope that doesn’t sound too confusing.

Any help greatly appreciated.
