i can't understand one thing.In the tutorials and the introduction for pyqt4 I see that there are windows and buttons and other visual things which obviously use the libraries from pyqt4.Am I correct so far?In which programs do these people write commands to make all these visual stuff and write code.What I mean is that if PyQT is not an actual program but powerful libraries if I understood well then how do they use them?For example:

a)if I am trying to develop a program in Fortran a useful tool for that job will be Fortran Developer Studio.It has an interface and gives me the opportunity to use plenty of tools which already has in order to program

b)On the other hand,I am trying to make a program which opens some specific programs(e.x.:utorrent,Word,My computer,solitaire and others)when the load of the os is finished.In that case a open the notepad i write a few commands,I save what I wrote as something.bat,I copy the file into the folder with other startup programs and that's all.I know there is a difference between bat files and actual programs enriched with visual effects,but the thing I am trying to say is that if I install PyQT and start to write a program I will a have to open a notepad and write code which in some spots will have coomands asking libraries from PyQT or there is another way to use them?

I hope you understand what I am trying to say.What I am asking is that I want something like Fortran Developer Studio enriched with tools for visual programming(you know ready dialogue boxes and other similar things)
