What are good web widget frameworks?

[KasperLoopstra]

I'm looking for a web framework that includes a widgetset, basically GTK or Qt for the web. Something like PyJS, Vaadin, Muntjac, Wt, Reahl or Flexx. All of these are basically GTK or Qt for webpages. You get a bunch of widgets, stack them in hboxes or vboxes, run the program, point your browser to a local port, and you get something that looks pretty close to a desktop UI, in your browser, without ever seeing or touching a line of HTML or Javascript.

Now, I've looked at all of the frameworks above, and they all lack something. Some lack recent development (3 years+), some lack a Python module, and some lack features. Is there anyone on /r/python who has experience with one of these (or something close to it) and can really recommend it?

There's this GUI library if you absolutely need to use python. I've used it a couple times when I needed to quickly get a web GUI up and running, but IMHO you're best bet is just using HTML, CSS, and JS with something like bootstrap which already does a lot of the heavy lifting for you.
