You can under gchart 2.7: http://clientsidegchart.googlecode.com/svn/trunk/javadoc/com/googlecode/gchart/client/package-summary.html#ChartGallery

Scroll down to the stacked chart with example code (it's basically a square pie chart).

You cannot at the moment create stacked bars using gchart with Google Web Toolkit using Java.
