HTML - WEB FORM running PYTHON SCRIPT

I'll second this.  Javascript is pretty comparable to Python in ease of learning, so that should be no obstacle.  As for keeping the code from being accessible, you can put the javascript in a separate file that's called from the guest's web page, but that's far from a foolproof method.  If you want the guest browser to do the calculation, there's no realistic way to keep the calculation code off of it.
