For relatively portable things to do with opening new windows and such,
I'd use the tcltk package. For example, a variation on demo(tkfaq):
tt <- tktoplevel()
tkwm.title(tt, "R FAQ")
txt <- tktext(tt, bg="white")
scr <- tkscrollbar(tt, repeatinterval=5,
command=function(...)tkyview(txt,...))
## Safest to make sure scr exists before setting yscrollcommand
tkconfigure(txt, yscrollcommand=function(...)tkset(scr,...))
tkpack(txt, side="left", fill="both", expand=TRUE)
tkpack(scr, side="right", fill="y")
for (i in 1:10)
tkinsert(txt, "end", paste("Done step", i, "\n"))
