You can remove layouts from layouts with the QLayout.removeItem() method.

You'll need to delete the contents of those layouts yourself - maybe that's
the real problem. You shouldn't need to redo the whole layout structure,
though.

These days, you'd probably use PyQt4's WebKit integration for HTML
rendering, anyway, though I imagine that it doesn't help you much if
you're already using WebKit directly.

You can write your own layouts as well, but maybe that's more work than
you're prepared to do, especially now that you seem to have settled on
WebKit as your toolkit.
