It isn't a general option, but there are a couple of specific window decoration sets that will let 
you resize those buttons.  Go to  appearance & themes -> window decorations and select
either "Glow" or "Smooth Blend".  Note that in order to adjust the button size upward in the
latter, you must first adjust the size of the titlebar itself, as it caps the buttons at titlebar - 4 px.
