It does "just work", you just get generic GUIs instead of
plugin-specific ones. 

There are some "port hints" in the plugin that specify whether a certain
parameter is interpreted as an integer, a boolean, has upper or lower
bounds etc that the host can use to decide whether it should use a
spinbutton or a checkbox or a slider or something else for that

You could look at some existing LADSPA hosts with GUIs (e.g. JACK-rack,
Ardour, Om, Hydrogen) to see how they do it.
