Bug 5765 New Class button in empty workspace should be more supportive
User feedback: "Confused how to create my first project" We should be more supportive in the UI for this special case since it is a first time experience with the UI. Therefore when the workbench is empty we should offer to create a new Java project. Minimal solution is to show an info dialog that explains that user should create a project first and offer a button to open the Java project wizard. The same is true for the new package and new interface buttons.
