HTML helps you lay out the content on the page, and style it.
To have a voting system, you will need to run some PHP code on the server to deal with the counting. That code will either need to store data in a file on the server, or it will need a dash of mySQL code to store and retrieve the data in a database. The code will also need to be protected from page refreshes artificially increasing the vote: by letting each IP address vote only once per day, setting cookies etc.
