Is there a way to grey out fields in a custom form so they are visible to everyone but can only be edited by an admin?

I am looking for a way to restrict editing of fields in a custom form.  I need the info in the fields to be viewed be all users but only edited by an admin.  Is this possible?

For the forms where I need this functionality, I'll typically have an Admin-Only section that contains the real fields that is visible/editable only to an Admin. Then I create calculated fields that display a summary of the data that the Admin has input, so everyone can see the calculation but not actually edit the input fields.
