Do you mean something like this? I am a newbie with R's tcltk too.
library(tcltk)
tt <- tktoplevel()
input.widget <- tkentry(tt)
output.widget <- tkentry(tt)
tkinsert(input.widget, "end", "4")
tkinsert(output.widget, "end", "24")
gui.fat <- function() {
n <- as.integer(tclvalue(tkget(input.widget)))
fat.n <- prod(1:n)
tkdelete(output.widget, 0, "end")
tkinsert(output.widget, "end", fat.n)
}
button.widget <- tkbutton(tt, text="fat() =", command = gui.fat)
tkpack(input.widget, button.widget, output.widget) # geometry manager
