Look at the code above and tell me what is readable and what can not be read.
now you know where the failure is. That is also where the layout is done and where your components loose ground.

Java

 Container mbmlauncherfataContentPane = mbmlauncherfata.getContentPane();

// init of components

GroupLayout mbmlauncherfataContentPaneLayout = new GroupLayout(mbmlauncherfataContentPane);
mbmlauncherfataContentPane.setLayout(mbmlauncherfataContentPaneLayout);
mbmlauncherfataContentPaneLayout.setHorizontalGroup(
  //fancy Layout
);

in the first line you are creating the ContentPane "mbmlauncherfataContentPane" with the ContentPane from the JFrame and create your own party. Fact is, that the JFrame is not invited and therefor does not take part.

Java

// Container mbmlauncherfataContentPane = mbmlauncherfata.getContentPane();

// init of components

GroupLayout mbmlauncherfataContentPaneLayout = new GroupLayout(getContentPane());
getContentPane().setLayout(mbmlauncherfataContentPaneLayout);
mbmlauncherfataContentPaneLayout.setHorizontalGroup(
  //fancy Layout
);

works much better.

You need to take care of some more things here:

Java

label5.setIcon(new ImageIcon("E:\\Chituri\\MBMLauncherJava\\src\\resursele\\dasdasdasd.png"));

Absolute Paths only work on your machine.

Java

mbmlauncherfata.setTitle("MBMLauncher");
mbmlauncherfata.setSize(305, 395);
mbmlauncherfata.setLocationRelativeTo(null);

same failure same result. You do not need to reference the Jframe as a object - you are working inside the JFrame.

Java

this.setTitle("MBMLauncher");
this.setSize(305, 395); // setPrefferedSize(new Dimension(height, width)) will do the trick, setSize does not work
this.setLocationRelativeTo(null);

works much better. to prevent that please delete the member variable "mbmlauncherfata" (line 186 of this code):

Java

// Generated using JFormDesigner Evaluation license - Ene Ion
//    private JFrame mbmlauncherfata; false reference
    private JTextField textField1;
    private JCheckBox checkBox1;

and please try to bring some readable sense into the GroupLayout - that looks nasty here and doesn't get better in a IDE.
