Ok let's look at some of the use cases you mentioned.
Wire up form submission: Submitting a form in just HTML requires setting the action attribute to point to a backend that will accept the form and do something with it. Wiring it up does not require knowledge of code, it requires knowledge of knowing where to post that form to. What kind of automation do you envision here?
Writing Javascript to get navigation bar working: Lots of widgets/controls exist with javascript based behavior enclosed with the UI(they even have extension points via properties that can change how the control behaves by setting properties e.g. slide left slowly, slide up with a bounce, etc). If you need your navigation bar to behave in a custom way there is no way around writing javascript to implement your custom behavior.
Setting up MySQL server to get dynamic content on the page: Unless you want to put MySQL connection code directly in the frontend(not recommended) you will have to write some code to get the data from the backend.
Now if your goal is to move away from hand-coding simple applications and Wordpress templates for creating simple Websites then the Title of your blog post is a tad exaggerated at best and a bit of link baiting at worst.
