I think you want something like this:
require(tcltk) || stop("Package tcltk is not available.")
version.BWidget <- tclvalue(tclRequire("BWidget"))
modify_command <- function() {
print("Hey, I'm modified...")
}
tt <- tktoplevel()
values = c("foo", "bar", "jeebee")
combo <- tkwidget(tt, "ComboBox", "-modifycmd",
modify_command, values=values)
tkgrid(combo)

For BWidget:
as.numeric(tclvalue(tcl(combo,"getvalue")))+1
I haven't used Iwdigets yet...
