Here's my attempt that uses the DataGrid approach: http://dougmccune.com/blog/2007/02/01/building-a-gantt-chart-component-in-flex/
It uses adjustable sliders, so you can adjust each item. It's by no means complete, but maybe it can be a start...

no problem, I figured it could work as a gantt chart even if it wasnt originally designed to do so... hope it works out.
