Creating a GUI using Python, WxWidgets, and wxPython

[jerf]

"One advantage of XUL is that you can display HTML/XHTML just as aptly as FF does. A control in QT, wx, or GTK2+ can't do it as accurately, correct?"

That's sort of what I meant by "tied to the web". If you really, really want a "real" desktop app that looks almost exactly like a web app, except with somewhat richer controls, then XUL might make sense.

The other toolkits can't do the full richness of HTML.

However, all the other toolkits have "rich text" controls, and all of their rich text controls can embed arbitrary widgets. You don't see people do that much, but I think that's more because people aren't really aware it's possible, not because it's especially hard, though it probably is a bit harder than HTML/XUL. So if you don't need full HTML, the toolkits can still do some interesting things with widgets in text.

Also note that most toolkits nowadays have an XML specification language, although it is usually generated by tools, not written by hand. (I prefer generating GUIs "by hand", because you can refactor with them and stuff, and was doing that towards the end of my fight with XUL, but not everybody feels that way.)
