In case you want a *transparent* (invisible) window, pass InputOnly as "class"
parameter to XCreateWindow
http://tronche.com/gui/x/xlib/window/XCreateWindow.html
If you want a *translucent* (partially transparent/translucent content) window
you require a running compositor (to see the translucency)
You'll also have to provide correct visual and colormap, see eg. here:

Cheers,
