No, at least not that I've ever heard whisper of. Pod is a very simple form of markup; it shouldn't take long to learn it.
That said, any decent text editor should be configurable to recognize Pod directives and apply syntax highlighting to them. If your editor does code-completion of keywords you'd get that too. (Note: code-completion wouldn't apply to a hypothetical WYSIWYG editor.)
As for seeing the output, there's no standard way of rendering Pod. It can be rendered as plain text, HTML, or anything else for which someone was written a translator. Depending on your text editor you could add a "user command" to translate the current document and show it in an appropriate viewer. For example, run it through pod2html and open the resulting page in Firefox.
Edit: The Hints for Writing Pod section of perlpod says
If you're more familiar with writing
in HTML than with writing in Pod, you
can try your hand at writing
documentation in simple HTML, and
converting it to Pod with the
experimental Pod::HTML2Pod module
which would allow you to use a WYSIWYG HTML editor to write documentation. (At least in principle; much would depend on what kind of output the editor produced.)
