 There are a number of development systems for different languages
 which allow you to build graphical user interfaces by drag and drop,
 including visual C++/CBuilder,  visual Java/Jbuilder, visual Basic,
 and visual Pascal/"Delphi".


 The advantage of basic is that it's simpler than the others to get
 into, but it's clunky and less powerful and less easy to get things
 done once you've learned it. There are no advantages at all to Pascal: 
 if you want a dinosaur, buy a brontosaurus. VBasic is like Cobol, there
 is an awful lot of software written in it and never rewritten even 
 though it's naff. Pascal is like RPG: **somebody** somewhere has a 
 load of legacy software in Pascal and won't let go, even though
 it's gutwrenchingly awful even to contemplate the stuff.

 The important ones are Java and C++, where the comparison goes....


 Java is intermediate code, it will always be slower than C++; C++
 always gives ultimate speed. Since it is intermediate code, Java is
 very portable between many machines and operating systems; C++ isn't
 in practice.  You can write the same app between different machines,
 but you'll mess around endlessly trying make it actually work on them.

 C++ is that bit more powerful and that bit harder to learn. C++ lets
 you do anything but that means it lets you make mistakes, and bad or
 unfinished C++ programs are murder for stuff like memory leaks; Java
 is more restrictive, but protects you from many errors and crashes.
 Java deals with the issue of classes better and more cleanly.  Java is
 definitely the nicer one to program in, though you may be less pleased
 with the ultimate performance of the result on your particular machine.
