Most of the work should be in implementing a QSyntaxHighlighter for Lua.

The other tricky thing is that there is no easy way to add syntax 
highlighting for a new language to Qt Creator at the moment. You will 
have to create a new plugin (say LuaPlugin), which adds a new derivative 
of the BaseTextEditor (say LuaEditor), with appropriate factory, editor 
action registration (TextEditorActionHandler), define and register the 
MIME type, etc.

I guess we could add a Highlight plugin, through which we could make it 
easier to add basic highlighting support for more languages, but at the 
moment this has no priority from our side.

Once you have your LuaPlugin, implementing custom indentation logic, 
code completion and navigation for Lua also becomes possible of course.
