Plumbing question

I need to install a dishwasher, which requires some source of cold water.
Been reading around on plumbing 'techniques' ... what is an easier method of getting water out of a copper pipe, without doing 'flaring' ?
Is there any kit out there which I can easily punch in and screw on ?
Thanks
