Other than a few specific packages, the windows versions should run without having to install any other software. There are both .exe installers and .zip file installers for the latest versions (4.0.3 being most recent.)  As Andreas said, please reply to the list with exactly which you installed.

Here are the official installers:

I believe there are also 64bit installers but I don't have the link handy.

Based on the usual experience with windows, I'd recommend fully uninstalling both gnuplot and octave.  I prefer to use the zip files rather than an executable installer. Just unzip it into C:\Octave, and you should be able to run (or manually create shortcuts to) the octave.bat file.  I haven't heard of anyone else having plot issues like you describe with those versions.
