You can do everything with a normal window, Jeffrey. Look up the right
functions, but you can:

1) Make de decorations disappear, leaving a clean rectangle.
2) Put an image on the background, with the black border you want,
   making it fill the window entirely,
3) Put a label in the center of that window, and enter the text you
   wish to show.

You might want to search for the many examples of 'splash screens' with
GTK available on the 'net.
