Building Qt from source?

Question

Qt

Warnings
Please do not throw me out on Google, I've already been there. I have never compiled Qt before.
Realization
Two days ago I realized that I needed to build my Qt applications statically. I've been tolerating these dlls for a long time... but my patience has run out. Rather, not patience, I have the task of building a standalone application.
My guesses
I know a little and read a lot. The result is the following algorithm:

1. Download Qt for Open Source C++ development on Windows. link
   
2. Download MinGW. link
   
3. Unpack sources and MinGW to 'C:/Qt' folder
   
4. Push MinGW into 'Qt:/Qt/[sources]/mingw'
   
5. Run 'configure.exe' with switches -static -debug-and-release -no-qt3support -no-exceptions
   
6. Run 'mingw32-make.exe' with sub-src command
   
7. Screw Qt Creator
   

My Questions
I am concerned about Qt Command Prompt. I can't find it anywhere in the source. It turns out that I need to set all the environment variables myself? Or are there other ways? You can write specifically stage 4-6 (from my list) as for a moron :).
And how to fasten Qt Creator? Is it enough just to download the binary and install it somewhere in the share? Or do I need to stir up something additionally
PS I know the noob question, but please do not downvote. And if possible, even plus :)
Waiting for answers, thanks.
