[Haskell-cafe] HTML - based GUIs - follow up

Hello, in my first post on this subject from 01-10-10 I asked for opinions on using HTML to create the gui part of a desktop app instead of using Gtkhs or WxHaskell. The responses were encouraging. It occurred to me that I might now even need to run an actual webserver (happs for instance) but that I could use either Webkit or a com interface to Internet Explorer to control the browser. When it opens, register event sinks and so on. Still that involves a lot of boilerplate code. I have seen examples of *formlets* and I'm impressed, the wiring is certainly taken care of. My question is: do formlets only work server based or is it also possible to use formlet sans happs? Günther
