You could try opening a new Word document, setting the margins so that you can only type within the size of your bounded boxes. Then type all your text, or copy it from your other word document, or set the columns on your existing word document, etc. After you have all your text formatted the way you want, I recommend not adding font and size elements, just lines, go in the Left edge of your second line, and put a hard return at the start of every line. Then open notepad, copy the text out of your word document into note pad, select all again, then copy and paste into PDN.
Once you have your text added to PDN, go ahead and change font/size/color/style, and move the text into the appropriate position.
In web design you would accomplish much easier by just creating a div tag and styling the div tag to the width you want it to be using CSS.
