You need to record your keyboard by plugging the audio outputs from the keyboard to the audio inputs on your PC soundcard. You will probably need an adapter to do this so you can plug 1/4 inch phono jack(s) into your keyboard and then plug that into the stereo mini jack on the input of your computer soundcard. Radio Shack or similar electronic stores have converters for a few $ that will let you do this. Then you need to record using software ( even using the Windows soundrecorder program that comes with Windows will work ) by putting it in record mode and playing on your keyboard while it is recording. You may have to try it a few times just to get the volume levels right. Once you have recorded the whole song then save it as a .WAV file. Then do the same again for each song you want to record. Then PC CD burning software can take those .WAV files and burn them as tracks on a CD. That's about it. It may take a little trial and error to get the levels right.
