Are you looking for something like this?

cbValue <- tclVar("0"); info<-tclVar("initial text")
top <- tktoplevel()
cb  <- tkcheckbutton(top,variable=cbValue,text="write or not")
en  <- tkentry      (top,textvariable=info,state="disabled")
exit<- tkbutton     (top, text="exit", command=function() tkdestroy(top))

    if(on.off=="1") tkconfigure(en, state="normal")
    if(on.off=="0") tkconfigure(en, state="disabled")

Do you know http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples?
