Can I use Dreamweaver to make a website like WordPress?

to go further than just quoting the names of the languages and techniques to be used... one must also be sensitive to the whole set of classes that will create, manipulate, organize, edit and display the data. starting with a system of exchanges and queries that is encrypted.

Beyond that, you have to think about the architecture you are going to deploy in terms of data structuring and the development model to be implemented (see concepts like MVC, SOA, MVP...)... but also and on the other hand you have to think about an approach concerning the administration of your CMS, (Decoupled CMS, Headless and so on...)

A CMS like Wordpress, is based on several years of experience and especially on a very active community which knew how to bring to this tool an architecture which allows him to remain evolutionary. And that's the key to keep in mind... Increment the system to allow it to evolve and adapt, without starting from scratch

Dreamweaver is a tool to create code.  Tools don't build websites, people do. 

If you have the necessary skills to code in PHP/MySQL, HTML, CSS and JavaScript, you can build whatever you want.  If you can't code, use an online site builder like Wix, Webflow or WordPress.
