The closest would be to use Create Text Prop in the Object menu to, er, create some text which Poser will see as a prop item. You only get the choice of 3 fonts, but you can assign materials, make them visible for rendering or export these items. They are flat 2d objects though and there is no way to extrude them to 3d in Poser (that I know of).

Reading up on Lightwave it should just be a case of making the lettering into a full 3d mesh and exporting as OBJ or FBX to get it into Poser.
