Dear Sarthi, 

If you aren't in need of the full power of GTK (which Michael's suggestion gives
you), you might want to look at the gWidgets and gWidgetsRGtk2 package which
simplify GUI construction a bit:

require(gWidgets)
gbutton("submit", cont=gwindow("example"), handler=function(h,...) {
 cat("your action goes here\n")
})

The gWidgets package has a vignette with more demos.
