There's not much you can't build with DW providing you possess the necessary coding skills for the project. Everything from shopping carts & blogs to responsive web designs, dynamic web apps, search forms, contact forms, content management systems, mobile phone apps, you name it... DW is a tool. Like any tool, it's only as good (or bad) as the person using it.
Before you can get the most out of DW, you need to learn all you can about coding fundamentals including HTML, CSS, Web Design Theory and to some extent JavaScript. Later as your skills improve, you'll want to tackle more advanced projects using PHP & MySql. Suffice it to say, these skills are acquired gradually over time. You must be willing to devote yourself to learning and practicing with code. For some people this can be a very rewarding pursuit. However, it's not for everyone.
If you have the desire, start with these.
