At this point, you've created the stub files you need to start coding StockWatcher.
In this section, you'll review the functional requirements and design the user interface.
Initially you want the StockWatcher application to do six things.
After studying StockWatcher's functional requirements, you decide you need these UI elements:
The design team has suggested the following additions:
GWT does not dictate how you lay out your HTML page. A GWT application can take up the entire browser window, as it does in the startup application, or it can be embedded in an existing page, as it is in the Build a Sample GWT Application page of this tutorial.
The StockWatcher application contains both static and dynamic elements. The Google Code logo and the header "StockWatcher" are static elements in the HTML host page. All the other elements are created programmatically using GWT widgets and panels.
At this point you've reviewed StockWatcher's functional requirements. You have a clear idea of what StockWatcher does. You know what UI elements you need to implement and how you want to lay them out.
Now you're ready to build the user interface using GWT widgets and panels.
