Hi Zhenya.
Looks like you're using some really cool technologies (I am a big fan of Spock!).
I am sure you can get this to work in LoadUI, but it will require you to learn a little more advanced stuff about LoadUI to do that.
For one thing, you can definitely use the GebRunner with Spock within LoadUI. The first thing you'll need to do is to add the Spock jar and any dependencies it might have (which are not already provided by LoadUI) into the ext/ folder (inside your LoadUI directory). Notice that LoadUI still uses Groovy 1.8 so you'll need a slightly older version of Spock.
Once you've done that, you should be able to run simple scenarios in LoadUI.
If you want to create new statistics, have a look at this page:

This is not very hard at all, especially when you can just start from any existing component (see the directory called script-components/ which contains all of the Groovy components that ship with LoadUI).
This post (that I wrote myself) might also help you get started with writing LoadUI components:
