Eeeehhhh, no, they are HTML widgets. You might as well ask for
SQL-statements that generate HTML widgets. It just doesn't make any
sense.

Yes, you want to make a Javascript app. That's fine and good. For that
you would likely want some sort of Ajax library. Grok isn't an Ajax
library, but you can use Ajax libraries with Grok if you wish.
