Create a Gantt Chart from a imported Calendar

Hi, 

I recently imported a production calendar from Google Calendar. The calendar booking room is the equipment that is required for production and the times are listed ie 9AM-10AM. I was wondering if I could then create a Gantt chart for project. I attempted to switch to Gantt view but it requires two dates columns. Is there a way to do this? It would be vary valuable for production planning and equipment forecasting.
