Make 'CreateComponent' a Lua function that parsed its arguments and
calls a corresponding C function.  In you example that would be
something like

function CreateComponent(t)
  local parent = GetComponent(t.parent)
  ...
  local c = C_CreateClockComponent(t.parent, t.name, ...)
  
end

and in C

Component *
C_CreateClockComponent(Component *parent, char *name /* ... */)
{
   /* ... */
}
