I also recommend python/pygame for stimulus presentation.
With the "psychopy" and "visionegg "toolboxes, you'll write a simple
reaction time experiment in just a few lines.
Be sure to save the data in a tabular format immediatly readable by R's "
read.table".
Alternatively, you might use "Rpy" to analyse the data.
