Anyone know how to build a very simple Gantt that you can actively edit to track progress?

Hi, I'm getting extremely frustrated in work trying to create a gantt chart for a project that could potentially be running until next year. The simple gantt template on excel is too complex as it goes into days. I'm trying to edit it so that I am only tracking by Q1,Q2 etc and the months of the year. Don't know how to edit it with all these formulas involved. Does anyone know of an alternative. I have tried to manually do it but can't.

Also, I would consider myself as a beginner with Excel - despite being examined on it in college!
