i am developing a java application. Now the code is running on the command line and i'm testing features.

Is there a way to be able to make the graphical interface using html5 and CSS3? I'm not very familiar with tools like JavaFX or similar.

For me it would also be good to convert the code to ajax / javascript to build a web-app, but in general I want to try to understand how everything works and if it is actually possible.

thank you so much!
