Sorry, you still haven't specified whether you want an audio CD (one that can be played in a CD player) or a data CD (one that can only be read using a computer).
If the former, then create a new playlist using the File/New Playlist menu in iTunes, select and drag the tracks into it, then click Burn in the top right corner. Before you do that though, make sure you go into Edit/Preferences/Advanced/Burning and check what you want to burn is set.
If the latter, then just use Goldwave to convert to whatever format you want (it does them all), then use the Windows CD burning Wizard to burn them to disk. Bear in mind WAV files are huge in size compared to mp3, as WAV is uncompressed. You'd be looking at Gigabytes of music for a couple of hours playback.
