That short answer is, yes that is possible. What you need to do though is
create a form and set a text area like this:
<form name="form1" method="post" action="">
<textarea name="textarea">PLACE TEXT HERE</textarea>
From here you can also set up the ammount of lines it will take before it
begins to scroll. This is very easy to find out how to do once you have set up
your form. Go to INSERT -> FORM -> TEXTAREA.
Let me know if this is enought to get you started.
