The Amiga widgetset is the 'mui'.

You can add a new widgetset in folder lcl/interfaces/yourws and use it
in your project.

For some nicer integration you can add an enum to
lcl/lclplatformdef.pas.

The IDE checks only the sources listed in the lcl.lpk. Since your files
are not listed there, changing any of your widgetset sources will not
trigger building the LCL package automatically. So you have to click on
the 'Compile' button in the LCL package.
