GWT Designer allows you to quickly create the modules, composites, panels, remote services and other elements that comprise Google Web Tookit applications.

I have a custom org.eclipse.ui.part.ViewPart with a TreeViewer in it.
I want to be able to drag and drop tree nodes onto the GWT Designer's DiagramEditor.
On drop, a GWT label and TextField should get created in the GWT Designer's DiagramEditor.
Can you tell me if this is possible and provide some guidance on how this can be done.
I am familiar with GEF and Eclipse plugin development (not an 'expert' though).

WindowBuilder does not support directly external DND.
But you can try to find active org.eclipse.wb.internal.core.editor.multi.DesignerEditor, get (in hackish way) EditEditDomain and set CreationTool which you want.
To install externally LayoutEditPolicy, which will accept your Tool, you can use org.eclipse.wb.core.gef.IEditPartConfigurator via org.eclipse.wb.core.editPartConfigurators extension point. See org.eclipse.wb.internal.swing.gef.policy.action.ActionDropPolicyConfigurator as example.
Actual adding of Label and TextField depends on target Panel you want to add them to. In general you should use org.eclipse.wb.internal.core.model.JavaInfoUtils.createJavaInfo(AstEditor, String, CreationSupport) to create model and then use FlowContainer or generic org.eclipse.wb.internal.core.model.JavaInfoUtils.add(JavaInfo, AssociationObject, JavaInfo, JavaInfo) to add new children to parent.
