Is it possible to create dynamic splash text instead of a splash screen?

I have a program (with its own main window) that every so often needs to display some dynamic text on the screen not just over the main window, but someplace on the screen. I don't want a background or any visible menus or borders, just the text. It seems like a splash screen might be the best approach, but please enlighten me!

Thank you
