You know, if you sit down and read this stuff, there's actually a *hell* 
of a lot of switches and options in there...

Like, you'd think creating a window would just be "hey, please create a 
window with this title please". But no. Apart from being able to specify 
the title, icon, and initial size and place, you can do a whole heap of 
other things:

- You can disable the close button.

- You can adjust the border style.

- You can remove the titlebar completely.

- You can enable or disable resizing the window.

- You can add that little help-icon thingy. You know, the one where the 
user clicks the help button, clicks something in the window and gets an 
error message saying "sorry, no help available".

- You can select "keep on top".

- You can select horisontal and/or vertical scrollbars.

- You can select whether whatever the window obscures is cached for fast 
redraw.

- You can enable file drag/drop. (I'm not kidding...)

- You can do that thing that floating toolbars have, where the titlebar 
is rendered smaller than usual and the window won't resize.

- You can have the window initially minimised or maximised.

- You can make it so the window can't become the active window. (I.e., 
you can see it, but can't select it.)

- You can "open" the window but have it invisible initially. (Presumably 
you'll make it visible at some point - again presumably once you've 
finished adding controls to it.)

This not including all the low-level stuff like what clipping to do, 
which drawing context to use, which window messages to send, and a bunch 
of other stuff I don't even comprehend yet.

And you thought you could just OPEN a window... ha!
