- The update url on the front page is wrong (issue 115), should instead be:
http://visualswing4eclipse.googlecode.com/svn/trunk/vs4e/

Use NetBeans instead

- Adds its own libraries to your project to support GUI creation.

Options no longer viable / available:
- Official “Visual Editor”, archived by eclipse: (Archived: June 2011), the matching install instructions at http://wiki.eclipse.org/VE/Update, and the outdated article / tutorial at http://www.eclipse.org/articles/Article-VE-Custom-Widget/customwidget.html, see also Is eclipse visual editor dead?
