App to simply display instructions?

Is there a way I can have an "app" that just displays a fixed text message?

So for example I've been using memtest, but Windows has a better memory test built in; so I'd like to replace the memtest app with an app that just shows the instructions for testing under windows.

Similarly for other apps, so I cant just fire up eg AkelPad to show a text file. (tried it AkelPad wont launch if i change its name)
