in reply to How to write standalone HTML GUI?

You could use Mozilla XUL, which is HTML(XML)/JavaScript User Interface. I am not sure if it works in conjunction with perl, since, I've several times started learning XUL, but every time got distracted by other problems in life. ...but it will only work in browsers, based on Gecko engine, unless something has changed since then.
