Essentially the answer is no. Django doesn't have a built-in representation of a view. You can't define a view in the same way that you would define a model, for example. This has long been on my 'things I want to look at' list, but I've never got around to it. You can define a Django model as a wrapper around a view by marking it managed, but that doesn't make the model read-only -- it just prevents Django from trying to create the model during syncdb. >From the perspective of the admin, you can define a field to be readonly, but that's purely a data display level concern, and is controlled on a per-field basis. With a bit of effort your could make an admin view that is effectively readonly, but there isn't a simple single switch to do this. Another approach is to use the databrowse app; that's purely a readonly display. It's not as mature or pretty as the admin, but it exists, and you might be able to use it.
