We don't normally look to add support for these kinds of things to the core GWT Highcharts API until the Highsoft folks officially releases the new chart type (e.g. it's not clear right now if this will be a completely new JS product, like HighStocks was, or if it will become part of the core HighCharts product line.)
If you wanted to get a jump on it though using their alpha JS release, GWT HighCharts is setup to support whole new chart types like this by extending the "org.moxieapps.gwt.highcharts.client.BaseChart" type. The "org.moxieapps.gwt.highcharts.client.StockChart.java" class provides an example.
I believe the existing "Point" class should then work fine to add data to the series, using the "setOption" method to set the fields needed for the gantt charts (e.g. "taskName", "depedency", etc.)
If you do decide to give it a go, please update us here so others can benefit. :)
