I've been working on core backend parts of applications since i've started my career, so i know quite little about the technologies of the User interface, can this book help me? what kind of background does the book expect?
In the book I look at user interfaces quite a bit. Chapter 2 is an overview of the GWT user interface library. There is a section on cascading style sheets, an easy declaritive way to add styles to your user interface, in chapter 5. Chapters 6-10 illustrate construction of 5 different applications using MVC architecture and a detailed look at each application's view. In other words you'll get an overview to get you started and plenty of detailed examples to pick up tips and techniques.
Let me know if you have more questions about using GWT for your interface. I could go on and on about how its a great tool. As for whether the book is for you to learn user interfaces, if you've been convinced GWT is the way to go, which I believe it is in many cases, then I think you'll find the book a great way to get started and get in depth.
