Gauges on a screen

Is there any adapter to make it where it can show guages on a screen, like Hptuners does on a laptop? I mean I guess I could buy a crappy laptop anf hook it up to the car and always have it running hptuners, but I was wondering if there was a simpler way. Oh, and heres a screen shot of the gauge thing im talkin bout from Hptuners.
