The RadGanttView control will come to a beta stage with the Q2 2012 release of RadControls which is expected at the beginning of June. It is not recommended to be used for production purposes yet, so I wouldn't advise you to use it for this project as some APIs might change and there will be missing features as the control is still under development.
Hope this information is helpful.
All the best,
