For well separated peaks, where no line fitting is required, you could adapt Graeme Ball's RDC macros (on the contributed software part of the CCPN site). Where you need to fit the lineshapes to extract couplings, a few of us have in the past cludged together a way to do this by calling out to the lineshape fitting part of the NMRPIPE package. There's a description in the email archives.
