My first hunch was that, since the program ends right after plotting, it
cleans up the plot window and exits. But trying it on an X11 system, I got
a persistent window despite the program exiting. That may be a difference
between Unix and Windows child process handling; I don't have a Windows
machine handy right now to test, but you could try this:
main = do
plot Windows $ Data2D [Title "Demo Title"] [] tData
_ <- getLine
return ()
If that doesn't fix it, my only guess is there's either a difference
between the Unix and Windows versions of gnuplot, or a bug in easyplot's
Windows handling.

A very simple test program with Graphics.EasyPlot, flashes up a window, but too fast to see it. There are several old posts on this issue with gnuplot, but I haven’t seen any current solutions.
Example:
import Graphics.EasyPlot
tData = [ (1,2), (2,3), (3,1), (4,5), (5,3), (6,1) ]
main = do plot Windows $ Data2D [Title "Demo Title"] [] tData
