wxGlade is not a full featured IDE and will never be one. wxGlade is just a graphical user interface builder. The generated code does nothing apart from displaying the created widgets.
wxGlade isn't a tool to learn programming with wxWidgets. You can't use wxGlade if you do not have any basic understanding of programming. You need to know the basics of wxWidgets, as well as the basics of C++, Python, Perl or Lisp.
