     Java can do it, pretty much.  Build a JFrame containing what you
want to display, and before displaying it use setUndecorated(true) and
probably setAlwaysOnTop(true).  Then use a javax.swing.Timer object to
make the JFrame visible/invisible at scheduled moments (you could do it
with a java.util.Timer, too, but the Swing timer is probably simpler).

     The "pretty much" part is that the method I've described will also
put an icon in the taskbar (if there's a way to avoid this, I don't know
it), so your "only a few words" requirement is not satisfied perfectly.
On the other hand, you imply that the user should be able to "pause or
exit the program," which suggests he needs *some* way to communicate
with it; a taskbar icon might be just what's needed.
