Is it possible to create a graphical interface of the website as well as in Android Studio?
In the same file write the HTML (you can live with CSS, you can separately), in another - js-ouuu logic. And all, all alone, like you wanted.
Plus I think with any thread of a build systems and preprocessors and all this can be even stronger post.

So it is well done. In HTML+CSS you describe the UI, and JS logic and the interaction with this UI. There is that interface designers (they are, but you do not wish to use it).
