Dev-C++ with wxWidgets designer
wxDev-C++ is an opensource wxWidgets Dialog designer that mimics the Delphi/Borland C++ Builder designer.
Yunus is a simple "visual" script language. Yunus is obsolete (left in 2004). However this site exhibits many projects; you will find my other "PHP, VS.NET, Flash, Delphi" projects. eOgr is my second complete application after Yunus.
