The gantt chart doesn't appear to be accessible at all via keyboard - this is important, and not just for blind people.
I would expect each gantt item (and control at the bottom) to be TAB-able, with ENTER performing the same as a click.
The left and right arrow keys could scroll the area horziontally, and +/- could zoom the scale in and out.
Full compliance with WCAG 2.0 to AA standard (and specifying ARIA roles for each element/control as appropriate) would be ideal but implementing my suggestions above would be a good step in the right direction.
