How can I import a single custom widget that I've created and make it so that it is not editable?

Thanks in advance!

Builidng the restricted application on top of an OEM Layer that does not include source files.

Thanks for your response Michael.
Your method is the typical way to make this happen. Is there a way to do this for say a single widget without embedding it in an OEM layer? I'm pretty sure I've seen it done but have not been able to duplicate it.

What Michael said. You can learn a bit more about this by checking out the following document and referring the section on Reusable Object Layers.
