Problem: how to add PATH

[Mursik]

Hello!
I have a problem. I'm trying to install GTK+ 2.22 (windows 64 bit).
It sais this:

To use it, create some empty folder like c:\opt\gtk . Using either
Windows Explorer's built-in zip file management, or the command-line
unzip.exe, available for instance at
ftp://tug.ctan.org/tex-archive/tools/zip/info-zip/WIN32/unz552xN.exe
unzip this bundle. Avoid Winzip! It is known to behave oddly.

(But you presumably already did extract the files, as you are reading
this file.)

Then add the bin folder to your PATH. Make sure you have no other
versions of GTK+ in PATH. Run:
pkg-config --cflags gtk+-2.0
and verify that it prints out something reasonable. Run:
gtk-demo
and verify that it works.

I have a problem: how to add PATH. I don't know how to do this and help wold be nice.
