MVCs work well for static HTML, but you asked for porting Tk which has far more possibilities than static HTML.

Thats why we pointed you to JS based Web UI frameworks.

But the discussion concerning the best way to realize DHTML within MVC is still evolving. (eg. MVVM ... etc)

Though I think you will just need to go with simple mojolicious and static HTML, and you just asked a XY problem.

But you'll need a good book about web-technologies to learn the basics or have a look at sites like http://www.w3schools.com/

As long as you are confusing Java and JS there is no help continuing this, perlmonks is not a site for web 101.
