Hi,
some Programms like WinonCD can do this on the fly, I'm sure there are more. In WinonCD just select an Audio-CD project, then drag and drop your MP3s and the programm will generate 'traditional' Audio-Tracks and burn them on CD.
If you have an CD/DVD that can play MP3, it's much better, because you can have ca. 10x more tracks on CD. Burning Audio CD from (rotten) MP3s gives no audio improvement.
