I couldn't find the way to get stdout and stderr of gnuplot for 
windows. If there is no way, TkGnuplot doesn't work on Windows. 
Because TkGnuplot gets drawing commands on canvas from stdout 
of gnuplot process. Of course we can get outputs of gnuplot by 
files on the disk drive. But it is not a strategy of TkGnuplot. 

If you use gnuplot as a drawing command generater for tkgnuplot.rb, 
you don't need to require an avility of drawing graph on the screen 
to the gnuplot command. Therefore, if you have a gnuplot command 
which cannot draw on the screen but can use stdin/out/err, you may 
be able to let tkgnuplot.rb work by the gnuplot command.
Although I don't know such gnuplot command working on Windows, 
cygwin version of gnuplot may be able to be used in this case.
