Hi, Nicholas, You'll almost certainly want to write a wrapper to create the plink command line and run it - a wrapper script can construct a correct plink command line and then do all sorts of post-plink transformation on the outputs as needed - which in my experience it usually is.
Most of the rgenetics tools do just that so looking at the source under tools/rgenetics may provide some prototypes you can change to suit your needs - eg rgQC.py and rgQC.xml Plink spews out all sorts of stuff so you may want to explore the Html datatype - see http://lists.bx.psu.edu/pipermail/galaxy-dev/2010-September/003311.html for a brief explanation.
