Yes, this all appears to depend on the plugin API used. Unfortunately,
some APIs can be really unwieldy, verbose and difficult to translate well;
this is presumably where the next suggestion comes in:

Another case is where the API is minimal because the plugin communicates
with the main application using a standard API, or perhaps a reference
to the plugin object is returned to the application, allowing it to call
plugin functions directly.

I've not looked at KControl yet, unfortunately, as I'd like to be able
to track down what is wrong with my panel applet. I suspect that my lack
of experience with sip is letting me down in a fairly fundamental way.

That means more time for me to debug and test it. First, I'd better look
at PyQt/sip/PyKDE 3.7.
