I'm using a frame parameter "undecorated" for this. On Windows it is
handled by the following function in w32fns.c:
void
x_set_undecorated (struct frame *f, Lisp_Object new_value, Lisp_Object old_value)
{
HWND hwnd = FRAME_W32_WINDOW (f);
DWORD dwStyle = GetWindowLong (hwnd, GWL_STYLE);
Lisp_Object border_width = Fcdr (Fassq (Qborder_width, f->param_alist));
block_input ();
if (!NILP (new_value) && !FRAME_UNDECORATED (f))
{
dwStyle = ((dwStyle & ~WS_THICKFRAME & ~WS_CAPTION)
| ((NUMBERP (border_width) && (XINT (border_width) > 0))
? WS_BORDER : false));
SetWindowLong (hwnd, GWL_STYLE, dwStyle);
SetWindowPos (hwnd, HWND_TOP, 0, 0, 0, 0,
SWP_NOSIZE | SWP_NOMOVE | SWP_NOZORDER | SWP_NOACTIVATE
| SWP_FRAMECHANGED);
FRAME_UNDECORATED (f) = true;
}
else if (NILP (new_value) && FRAME_UNDECORATED (f))
{
SetWindowLong (hwnd, GWL_STYLE, dwStyle | WS_THICKFRAME | WS_CAPTION
| WS_MAXIMIZEBOX | WS_MINIMIZEBOX | WS_SYSMENU);
SetWindowPos (hwnd, HWND_TOP, 0, 0, 0, 0,
SWP_NOSIZE | SWP_NOMOVE | SWP_NOZORDER | SWP_NOACTIVATE
| SWP_FRAMECHANGED);
FRAME_UNDECORATED (f) = false;
}
unblock_input ();
}
where FRAME_UNDECORATED (f) returns false if f is currently decorated.
If the `border-width' parameter is 0 the frame gets no border, otherwise
it gets the standard Windows thin-line border.

You can use the `left', `top', `width' and `height' frame parameters for
that.
