I want to know if it is possible to record my composition direct from Notworthy to rewritable CD. Can anyone help please?
Not sure of what you mean.
If you want to save your NWC files directly (as FILES) on a CD-RW support, it can be done as on any magnetic media if your CD-RW is formatted as a re-writable media.
If you mean recording it as an AUDIO track, it can be done as if it was on a CD-R. But you have to know that many CD-readers cannot read CD-RW media --it's not related to the format, but to the reflection/color of the disk itself.
BTW, I didn't try myself to record audio tracks on a RW, not (yet) being sure to re-use the RW support; theoritically, it should be feasible anyway, so I'll try it some day :)
If I did not answer to your question, could you please ask it again more "detailed" ?
