A new "partition table" will erase all the partitions in the actual partition table, so that the disk will appear empty. (data on the drive aren't automatically deleted, it is often possible to restore them with the "testdisk" software, if we don't do any further operations on the drive).
To make an all-windows system, you can delete the actual partitions (or make a new "msdos" partition table) and install vista from zero (of course, you need to take backup of any important previously existing file on the drive).
To dual-boot into mswindows and a Linux system, it is usually easier to start from mswindows, and then install the second system in a next step. So, if you don't have many data or software installed (I think so, by the photo you provide above), starting from vista and dual-booting is an option.
There are some guides on the web, to dual-boot with Linux installed first. You can find them with a google search. This way is relatively more complicated (at least with earlier windows versions). However this is an option to consider with systems with a lot of data and software on them and/or lots of customizations.
In any case, you can't use GParted installed with Ubuntu, because you need to work on the same partitions as the running operating system. So, you need to use the GParted livecd.

*** It is highly recommended to backup any important files before doing resize/move operations. ***
