If you mean you want the text fields to not be editable in the app itself, you could use labels instead, which can be found under User Interface -> Label
Right now, I assume you are using TextBox, right? These can indeed be modified by the user, whereas labels remain static unless the code changes them.
For scrolling, you could use the ScrollArangement layouts found under the Layout tab.
As a side note, I'm not sure if right now it is possible to add more Labels via script. It might be that the only solution right now is to create a fixed number of Labels, and fill them with text using scripts. Maybe someone else could clarify on this.
