  This is the principal function for creating any type of window in MEWEL.

Parameters
  szClass is the name of the window class. It can be the name of a
user-defined class or one of the following predefined classes :

    "NORMAL"    "BUTTON"                "EDIT"          "LISTBOX"
        "SCROLLBAR"
    "STATIC"    "PUSHBUTTON"    "CHECKBOX"      "RADIOBUTTON"   "TEXT"
    "FRAME"     "BOX"                   "ICON"          "COMBOBOX"

  szWindow is the title of the window.
  dwStyle is the style bits for the window (WIN_HAS_BORDER, etc).
  x and y are the screen-based coordinates of the upper left corner of the window.
  width and height define the extent of the window.
  attr is the color attribute of the window. It can be the constant
   SYSTEM_COLOR if you are using the system defined colors.
  id is the control id of the window (especially important for controls).
  hParent is the handle of the parent window, or NULLHWND if there is no parent.
  hMenu is the handle of the associated menubar, or NULLHWND if no menu is defined yet.
  hInst must be 0 for now. This parameter is in here for MS-WINDOWS compatability.
  lpParam is a user-defined value, or NULL. This value will be passed
   to the window procedure when the window is created - the window
   procedure will receive a WM_CREATE message with the value of lpParam
   passed in the lParam parameter. Important- in order for the WM_CREATE
   message to be sent to a window, it's window class must  be registered
   before the call to CreateWindow().

Returns
  The window handle of the created window if successful, NULLHWND if not.

NOTE: You should use CreateWindow() to create all control windows.
