Setting Up a Webinar

Hi, I have a one pro account, but just want to set up one webinar of an event than will run for a few hours, so those who can't make it can join in. Can't be complicated I thought. Everything I've looked at says go into 'Webinars' and access it from there, but there's only links to more complication and faff. Can someone help please, it would be much appreciated ! Ta Tony
