Display tweets with special hashtag and a manual update button


Hello guys

I have been trying how to do for my project. To do something like to display tweets with a special hashtag on my website. For example, #birthday, the latest tweets of #birthday will show on my website. And the tweets also will be updated every minute. May I know how to do like that?

I know there are widgets available from Twitter apps but there are no manual update button. As I want to make it purely without widgets. Is it possible? If yes, please share the link or guidelines where I can learn.
