I'm sorry, but I can't understand exactly what you are posting.
Google translator has problems when translating text with lots of terms not in general use.
Qt Creator (latest version is 3.1.1) is a standalone application that can use lots different compilers and debuggers (including those included in VS3013) together with lots of different Qt versions.
But if you don't have a precompiled Qt library, you'll have to first compile it from source after you configure it for the compiler and target device you want to use.
Problem is that Qt 4.8 (latest version is Qt 4.8.6) is available in precompiled form only up to VS2010, if you want to use it together with the VS2013 compiler you will have to first compile it from source (Qt 4.8,6 has a mkspec folder for VS2013 so you can at least give it a try).
If instead you are trying to use the VS2013 IDE to develop using Qt 4.8, you will have to manually set all include paths and libraries because the "Visual Studio Add-in 1.1.11 for Qt4" supports at most VS2010.
