This is just a prototype and doesn’t handle all the cases that a standard gantt chart should be handling. I would strongly recommend testing the code thoroughly before you start using it in production (if you are planning to, that is) I am unsure how much time I will be able to spend taking this project forward. I have opensourced this one under MPL, feel free to take the code and do more stuff as you guys deem appropriate. Please note that this is a resultant of a few hours of careless hacking , I am sure this has a lot of bugs too. I plan to set up a GitHub project for  the same, just thought I’d post it anyways.

Select a color from the swatch panel to change the background color of the Application.

You can download the source code (as fxp) here (There isn’t a lot of code, and usual caveats apply as this is just 30 minutes of work and is vastly untested:) ) TODO’s include allowing customization of itemrenderer sizes and regular skinning capabilities of Spark controls. Will do those iteratively.
