Ganttproject please

"With GanttProject you can break down your project into a tree of tasks and assign human resources that have to work on each task. You can also establish dependencies between tasks, like "this task can't start until this one is finished". GanttProject renders your project using two charts: Gantt chart for tasks and resource load chart for resources. You may print your charts, generate PDF and HTML reports, exchange data with Microsoft(R) Project(TM) and spreadsheet applications."

Perhaps a launcher to work with Freemind (https://portableapps.com/node/10952)
Or a launcher that uses java in common files like Babiloo (https://portableapps.com/node/11610)

Is this being looked at all by devs?

GanttProject Portable has been available for quite a while now.
