Unfortunately when it comes to learning how to create a web application from scratch, designing your own database and adding complex featues, there will be a learning curve. Giving up is always an option when facing anything you have never done before.
You can join tables with an INNER JOIN statement. You won't need complex or advanced SQL, just the most basic concept of any relational database. If you aren't prepared to learn basic concepts of php, mySQL, Dreamweaver, and webassist products, or you don't want to spend time trying to get stuff done, then by all means give up.
People that are successful with WebAssist products are prepared to learn a little mySQL in order to build a database application and aren't afraid to try to get stuff done. Since you can build any application you want, the steps are up to you, so you could never find step by step instructions on everything you can build.
