Why don't you look at the code for one of the many open source twms out there and figure it out?

#define MAX(a, b) ((a) > (b) ? (a) : (b))

int main(void)
{
    Display * dpy;
    XWindowAttributes attr;
    XButtonEvent start;
    XEvent ev;

    if(!(dpy = XOpenDisplay(0x0))) return 1;

    XGrabKey(dpy, XKeysymToKeycode(dpy, XStringToKeysym("F1")), Mod1Mask,
            DefaultRootWindow(dpy), True, GrabModeAsync, GrabModeAsync);
    XGrabButton(dpy, 1, Mod1Mask, DefaultRootWindow(dpy), True,
            ButtonPressMask|ButtonReleaseMask|PointerMotionMask, GrabModeAsync, GrabModeAsync, None, None);
    XGrabButton(dpy, 3, Mod1Mask, DefaultRootWindow(dpy), True,
            ButtonPressMask|ButtonReleaseMask|PointerMotionMask, GrabModeAsync, GrabModeAsync, None, None);

    start.subwindow = None;
    for(;;)
    {
        XNextEvent(dpy, &ev);
        if(ev.type == KeyPress && ev.xkey.subwindow != None)
            XRaiseWindow(dpy, ev.xkey.subwindow);
        else if(ev.type == ButtonPress && ev.xbutton.subwindow != None)
        {
            XGetWindowAttributes(dpy, ev.xbutton.subwindow, &attr);
            start = ev.xbutton;
        }
        else if(ev.type == MotionNotify && start.subwindow != None)
        {
            int xdiff = ev.xbutton.x_root - start.x_root;
            int ydiff = ev.xbutton.y_root - start.y_root;
            XMoveResizeWindow(dpy, start.subwindow,
                attr.x + (start.button==1 ? xdiff : 0),
                attr.y + (start.button==1 ? ydiff : 0),
                MAX(1, attr.width + (start.button==3 ? xdiff : 0)),
                MAX(1, attr.height + (start.button==3 ? ydiff : 0)));
        }
        else if(ev.type == ButtonRelease)
            start.subwindow = None;
    }
}

done

Could I have that in Ruby

Here you go:

 1.upto(100) do |i|
      if i % 5 == 0 and i % 3 == 0
        puts "FizzBuzz"
      elsif i % 5 == 0
        puts "Buzz"
      elsif i % 3 == 0
        puts "Fizz"
      else
        puts i
      end
    end

quite easy, tinywm is the minimal example:
Xlib - http://incise.org/tinywm.html
xcb - https://github.com/rtyler/tinywm-ada/blob/master/tinywm-xcb.c

dwm (Xlib) and 2bwm (xcb) are both very tiny wms to look at

a little late to start writing software for it, don't you think?
