It's a work-in-progress(super-raw proof of concept). Frontend is a JavaScript Chrome extension and backend is a C transpiler. We use the Treesitter C lib to parse syntax trees and the Mongoose C lib to handle websockets.

GitHub repo has a Java demo showing possible import syntax. Some keywords like 'from' and 'as' don't exist in Java. I found some workarounds. Please let me know what you think.
