In recent weeks I return to develop in C++, but my lastest experience was in Visual C++ 6.0 using MFC library for my undergrade thesis. Now, I must to do some application in C++ but I need to develop in an opensource IDE with opensource and multiplataform GUI. In conclusion I just going to share my experience using the minimum effort way to develop any application in Windows. The software that use was: First, we must install wxPack, this application install wxWidgets Compiled 2.8.9 (GUI library), wxAdditions and wxFormBuilder (GUI designer to wxWidgets).
Second, we must install Code::Blocks and when the instalation program ask us about wxWidgets path, the default path is "C:\SourceCode\Libraries\wxWidgets2.8".
Finally, let's go!, the framework is ready to use it! only you must to create a project and choice GUI Category and use wxWidgets project.
