That site seems to recommend much of the same - I would go for the System Rescue CD if you can stomach a 128MB download.
It is Linux based, but you won't need to actually know anything about Linux to do this. It's the one I've used to resize my NTFS partitions and it's never had a problem.
Simply pop it in and boot from the cd, type 'menu' to get a graphical setup screen. Set the appropriate options using your cursor keys and space bar if needed (like language for your keyboard) then tell it to boot.
You'll get dropped to a command line (like a DOS prompt) and all you have to do is type
run_qtparted
to get you the partition manager. I think that's the right command, but if you start typing run_qt and hit
a couple of times it will autocomplete.
You should see a partionmagic-like interface and you should have a mouse cursor too. It's simple and very effective in my experience. If for some reason the mouse isn't working, tab space and the arrow keys will see you right. Delete the second one, resize the first and then commit your changes when you're done.
Simply quit and then type
shutdown -r now
to reboot.
Usual caveat - this is all at your own risk of course 
Other ones on your website - Ranish is very powerful, but not as easy to use as the above programme. As for NTFSResize, QTParted already uses it in the background so that's not an alternative.
Hope that helps!
