Hi.
If you want to do it completely in R you can create R gui using gWidgets
package.

Here is an example of creating gui for function arguments (thanks to John
Verzani):

library(gWidgets)
options(guiToolkit="tcltk")

##' An editor for an argument
##' depends on calss of object
arg_editor <- function(x, cont, ...) UseMethod("arg_editor")
arg_editor.call <- function(x, cont, ...) arg_editor(eval(x), cont, ...)
arg_editor.name <- function(x, cont, ...) arg_editor(eval(x), cont, ...)
arg_editor.numeric <- function(x, cont, ...) gcombobox(sort(unique(x)),
editable=TRUE, coerce.with=as.numeric, cont=cont)
arg_editor.character <- function(x, cont, ...) gcombobox(sort(unique(x)),
editable=TRUE, coerce.with=as.character, cont=cont)
arg_editor.factor <-  function(x, cont, ...) gcombobox(sort(unique(x)),
cont=cont)
arg_editor.logical <- function(x, cont, ...) gcombobox(c(TRUE, FALSE),
selected=2 - as.numeric(x[1]), cont=cont)

## This replaces ggenericwidget
make_gui <- function(FUN, parent) {
  args <- formals(FUN)
  if(missing(parent)) {
    parent <- gwindow("Some GUI", visible=FALSE)
  }

  g <- ggroup(cont=parent, horizontal=FALSE)

  lyt <- glayout(cont=g)
  n <- length(args)

  f <- function(i, nm, x) {
    lyt[i,1] <- nm
    lyt[i,2] <- arg_editor(args[[i]], cont=lyt)
  }
  mapply(f, i=seq_along(args), nm=names(args), x=args)

  bg <- ggroup(cont=g)
  gbutton("ok", cont=bg, handler=function(h, ...) {
    values <- lapply(lyt[,2], svalue)
    nms <- sapply(lyt[,1], svalue)
    names(values) <- nms
    do.call(FUN, values)
    dispose(parent)
  })

  visible(parent) <- TRUE
  invisible(lyt)
}

## Try it out
s <- function(x=1:4, y = letters, z=TRUE) {
  print(list(x, y, z))
  assign("x",x, envir=globalenv())
  assign("y",y, envir=globalenv())
  assign("z",z, envir=globalenv())
}

make_gui(s)

You can easily adjust this example to your needs.

If you want you can use Excel, Access in order to create front end
application and using commandArgs to supply  arguments to an R script when
is invoked.
Examples of calling an R scripts from Excel and Access you can find here:
http://www.slideshare.net/djandrija/excelr
http://www.slideshare.net/djandrija/r-and-access-2007

Also, shiny package can be useful here (http://www.rstudio.com/shiny/),
integration of html, php and R...

Hope this helps.
