It is not possible to use any language and almost any technology.

I say practically because it is always possible for someone to install something that goes over a fundamental restriction in a browser. But do not count on it, the chance of this happening is almost zero. And if you persuade someone to install something that makes them vulnerable, you'll still have to provide that technology. That is, use another solution.

Doing things for web , contrary to what many people think, really is not the solution to every problem.
