Hi, we haven't been able to come to a conclusion with regard to the GUI yet, but that shouldn't keep you from starting to work on layer locking. It probably makes sense to start implementing this from the bottom up. Whether you then add a GUI for it into the layer row or somewhere above the layer list, doesn't really matter much. It will be easy to change later if there's a need to do that.
So, to get you started, why not add locked flags to the GimpLayer object and make sure that they are correctly respected by the rest of GIMP? You will probably also want to add a PDB interface to the new layer properties. Please ask whenever you need help. It is a lot easier to ask a few questions than to poke around in the source code for hours.
