Creates a TWS base widget in window WID. This widget will contain the
buttons in a grid with COLS columns and LINES lines. A uname (=user name)
may be given to this widget for later reference, which is currently useless
since the base widget doesn't return any event to your handler.
After having called TWS_INIT once, you can had buttons with
TWS_BUTTON. Buttons will be drawn bottom to top and left to right in the
