Ben,
Yes, it is easily possible. I have personally used Matrix Orbital serial LCD displays and QSI serial LCD displays. QSI also offers touch screen modules (I experimented with one very briefly). For information on a QSI Display with touchpad, see the following link:

QSI (www.qsicorp.com) also offers other types of displays that have been successfully used with FP-RT controllers. There should be other LabVIEW drivers available from their web site for some of their other displays.
