Welcome to the JavaRanch, Mogan. This really isn't the right forum to ask that question, since there's nothing JSF-related about what you want to do.
I'd also be careful about doing this. IE is no longer the One and Only browser, and not all of its competitors are subject to the same limitations. I use Firefox under Linux for example, and the spell-checking comes with the browser, so any attempt to bolt on a second spell-checker could potentially have problems.
Customer surveys are for companies who didn't pay proper attention to begin with.
