org.locationtech.udig.filter.ComboExpressionViewer
Use a Combo to edit CQL Expressions; the options in the Combo can be any Expression.
Internally we have a JFace ComboViewer tricked out to provide nice representations of various options (Expression.NIL represented as "(None)" for example).
We have helper methods to seed the available options from common cases such as numbers (for size) or colors, or a FeatureType to get all the property names listed.
Remember that although Viewers are a wrapper around some SWT Control or Composite you still have direct access using the getControl() method so that you can do your layout data thing.
