Yes, from a Lisp program.  But then it is under programmer control.

Only the menu-choice, coding-system and color widgets[1] call
widget-value-set as a result of a user action, so only those are
inherently unsafe.

[1]  The radio-button-choice widget also call widget-value-set, but it
doesn't rewrite itself when that happens.
