wxHtmlWindow is capable of parsing and rendering most simple HTML tags.

It is not intended to be a high-end HTML browser.  If you're looking for something like that try http://www.mozilla.org - there's a chance you'll be able to make their widget wxWindows-compatible. I'm sure everyone will enjoy your work in that case...
