You didn't mention your scripting language and database format, so here are some common but useful links to help you, generally speaking:

PHP and MySQL:

PHP, MySQL, Ajax (JavaScipt)
http://www.dhtmlgoodies.com/index.html?whichScript=ajax-poller

Flash, MySQL:
http://www.phpjabbers.com/web-poll/flash-poll-mysql.php

The first choice is by far the easiest to implement. The others get progressively harder. Note, there are literally a million ways to do a poll, wait for others to reply here with ideas before deciding. If you are unfamiliar with PHP and MySQL, part of a standard LAMP setup, please visit this link for a novice tutorial plus other platform suggestions:
