I've seen this request numerous times in the community - in fact I had it myself. To my knowledge, there is no way to accomplish this outside of actually coding.
I went to the user voice, and surprisingly did not find many posts about this, however the one I did find about having a pop up window for a new record, was marked Declined. Perhaps not something QB has any intention of taking on natively...
