Using Google forms as a poll on twitter is possible and in fact very easy. It works in a way that when you tweet a link to a Google Form, Twitter will then embed the actual form on the tweet and it shows when the tweet is expanded.
Here is a live example of a tweet with poll from Google Forms.
All you have to note while doing this is to make sure that your poll is short – simply because twitter has a character limit and therefore Twitter will only display a question or two which most people will not know how to move over to other hidden questions – The hidden questions can gotten to using the TAB key. Also you should make sure you use small fonts and don’t use any description text instead do that in your tweet.
