Google Calender Integration

I need my google calendar to integrate with a calendar widget for my website. My website is: dereksellersmusic.com. I want a calendar widget to look like the one that I currently have, but I need to be able to edit the design, be able to embed it, change size (dimensions), etc. The calendar needs to be able to pull events, times, places, etc. from my google calendar into the calendar on my website. So if I add an event to my Google calendar, it will automatically post on my website. When an event ends (date/time passes) it should remove itself from the widget on my website. So if I had an event for March 23, 2013, 6:00pm-9:00pm, it should not still be in the calendar on my website. It should be a very small project and should not take much time. I would like to see it testes and can give code to the current event calendar to speed things along. Please respond and give quotes. Thanks so much.
