That's quite a mean feat you wish to accomplish. Your best bet is to either use a rich text edit box, or, better yet, something that supports HTML and then copy the Word data as HTML.

MS-Word does support exporting your document as an HTML document, which is probably the closest you'll get to being able to do this.

MS Word does use a proprietory format though, so you might not get to represent the document 100% as you see it in Word.
