首先去官方下載：
//官方網站 http://www.gtk.org/download/index.php //下載鏈接 http://win32builder.gnome.org/gtk+-bundle_3.6.4-20131201_win64.zip http://win32builder.gnome.org/gtk+-bundle_3.6.4-20130921_win32.zip

看懂英文的話，那個文本文檔里有安裝說明。
To use it, create some empty folder like "c:\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+-3.0 and verify that it prints out something reasonable. Prepare Pango : pango-querymodules > c:\gtk\etc\pango\pango.modules Prepare GDK-Pixbuf : gdk-pixbuf-query-loaders > c:\gtk\lib\gdk-pixbuf-2.0\2.10.0\loaders.cache Prepare GTK+-IMModules : gtk-query-immodules-3.0 > c:\gtk\lib\gtk-3.0\3.0.0\immodules.cache Run: gtk3-demo and verify that it works.
