Freeware C or C++ GUI?
Are there any freeware C or C++ Grahical User Interfaces available? I mean sth like Microsoft Visual C but free. That you can use visual interface, add buttons or text fields visually and so on, not only a code window...
Or are there only paid versions of thing like this?
You can download DJGPP. There are, I believe, more then one IDE to go with it, Rhide is a common one. There is a link to the download site from the "Compilers" section in the FAQ. There are other as well.
The learning edition of MS VC++ comes with some books. Deitel and Deitel for example.
IF you mean a graphical resource editor, you can use LCC-win32: http://www.cs.virginia.edu/~lcc-win32/
