I wish to add a voting form to very basic one page site, the site is not important but the vote is, basically i want people to vote and add their support to a proposal i have in mind, obviously i don't want anyone voting twice as accuracy is essential, and their name added to the list would need to be confirmed via an email, click link to confirm sort of thing, this would be similar to the uk. government online voting system.

How would i go about that?
