The examples provided on the official website are not detailed enough and hard to learn for me,  
so Is there a more detailed tutorial on creating custom slicer application? step by step tutorial and examples, video tutorial will be more better!

There are some on youtube. For example this one:

As far as I know there are no tutorials.  
@moraleda the video you linked is about creating an extension, which is different than the question was.

@iwangwangwang You need to follow the steps to create a Slicer custom app skeleton from the template

Then you need to build it just as a Slicer build. You need to add your own modules to the source tree in `Modules/` and add them to the main `CMakeLists.txt` file. Those modules will then be part of your application. You have all the freedom customizing the app, by hiding the toolbar etc.
