sorry about the confuse
the application does not need to install, juz clicked the .exe file, then it will run.
The two .dll files are come from qt package. Qt is an interface api, i use it instead of windows api, coz I am not a windows programmer, beside I am a linux programmer, therefore, i have to use this api for cross-platform support.
I will upload some pic if require.
