I have to say, I was one of the biggest fans of Wings in the world. I loved winged edge modelling suites, going back to Nichimin n-worlds, the app that ultimately inspired Wings. The said... Wings3D is a dead end. Development ended and it's really starting to show...
If you want to learn 3D modelling, without a budget, consider giving Blender a shot instead. The interface isn't as daunting as people make it out to be, with BMesh being added, the worflow is similar to what Wings was like ( superior now actually ). Plus, I have an
end to end tutorial for you if you are willing to dedicate an afternoon to it.
You aren't going to find many tutorials, at least not current ones, as Wings has basically been dead and abandoned for over 2 years. If you want a similar feeling/simplified experience, try sketchup instead.
