Tcl/Tk provides window managers to specify widget layout. Two most used are 'pack' and 'grid'. Each has its merits, but 'grid' becomes more advantageous as UIs start to become elaborate. Of course (tk ...) works with any Tk window manager, but 'grid' has been successful and at this point well integrated into the project.
