QT based application design and development issue

I am new to the Qt framework and am trying to develop one application. I have one text file which contains around 800 fields(bool,int,dbl and string) which is called setting and parameters file. To edit this file and to send these params over serial i need to develop application.For this i have developed 35 screens to edit and to show data.So am requesting you to help me to understand design patterns and architecture for this kind of application.

For this am thinking to use one model(custom) and multiple views option.Please suggest me how to proceed and how to develop custom model of mixed datatype.

Thanks in advance.
