If you have XWindow based boxes you may use tk package and even to use graphical user interface (for example DialogBox as parameters input) on remotex boxes from pltclu (sometimes I do that). For external ETL I am using Java Eclipse or Eclipse RCP Framework and embeded python language (formaly jython) - very important fact is that jython scripts may controlled Eclipse widgets (for example ProgressBar).
