Maybe try Freemake - free download
I have used both of these and, as far as I know, they are 'clean' downloads.
Although Audacity is an audio editor, you can just open an audio file, then 'Save As' MP3, then close. It's very quick. You would then need a CD burning program to burn the file to CD.
I can't think of any program you could convert and burn with but, if there is one, I'm sure someone will be posting in due course
