How do I get audio on speakers and cue in headphones only?

I'm sorry, I'm sure this has been asked and answered but I wasn't sure how to look.
I have Cross DJ and a Lenovo Thinkpad- If I buy a headphone splitter will the program know to put the audio out of one aux channel and play only the hidden cues in the other?
Are there any speakers I need to buy to do this?
My laptop also has bluetooth and I have a bluetooth speaker, can I have audio simultaneously streaming to the Bluetooth and the headphone jack?
Is this making any sense?? Sorry I'm so confused
