I have one that that is just called morse.exe. It is a single file that does not install anything. It is freeware with no license requirements. If you want to PM me with an email address I would be happy to email you a copy because I don't remember where I got it.
If you don't like it, just delete the file and it's all gone. It does not install anything on your computer.
The simple believeth every word: but the prudent man looketh well to his going. ~Proverbs 14:15
