I'm new in Java, especially the User Interface part, and I wanted to show the different problems that I come across in order to fix them.
1- When I start the application, that's what I want it to be displayed :

However, this is what happen evry time I lauch the application:

I have to put my mouse where the button is to be able to display it
2- When I minimize the application and go back, this is what happen:

3- When I'm starting the processing of my data, I want the interface to display the current state of the application (how many percentage for example), like this:

However, this is only happening at the end of the operation. Meanwhile the process, I think my interface just freeze, and it's giving me this instead:

I have no idea why all of this happen. Apart from this, my application works perfectly, and does what I'm programmed to do. This is my Interface class:
