Is there a plugin to add events on Google Calendar?

Hi, I’m new to WordPress and I would need a way to add an event to a Google Calendar at the same time I create a post (with every new post there is an event). Is there a plugin or widget to do it? Sorry to ask but I have been looking around in widgets page and havent see anything like that. Myabe is not possible, I dont know, but as I’m new at wordpress I still dont know what exactly I’m able to do. I can change/update wordpress version if needed.

Thanks!
Josep
