The opposite, if you select gtk2-x11 which requires X11 then X11 is 
selected additionally automatically by setup.exe.

The problem is: setup selects automatically to install packages which
are required by another package, but it doesn't handle the other way

not deselect other packages which are requiring the manually deselected
package.
