Is it possible to write a standalone GUI in HTML/DHTML (i.e. just using web browser, no web server) to execute Perl scripts?

For example, have a web page with a bunch of links to my Perl scripts, which I can click and execute, and see the script's output in the browser, without resorting to web server and CGI. Rather like a standalone browser-based shell.

It seems easier to me to write a GUI in HTML than Tk, plus you get CSS stylability and all that.
