Not necessarily.

The standard Xt-based widget sets (Athena, Motif) are both fairly
basic, so it's common for non-trivial applications to create
additional widget classes as necessary.

When creating additional widgets, I think that the key is to "go with
the grain" of the native widgets. I.e. base the new widget class on an
existing one (e.g. Motif has XmPrimitive and XmManager widget classes,
which exist solely as a base for more specific classes), and honour
any established conventions.
