Only a title bar pops up when im trying to access a GUI from another class via button

i'm a newbie programmer and im kinda stuck with this issue for 2 hours now. So my issue is that whenever i click the Register button, only a title bar (no contents at all) pops up in the upper left of my screen. How can I fix this? Thank you in advance

btnRegister = new JButton("Register");  btnRegister.addActionListener(new ActionListener() {  public void actionPerformed(ActionEvent e) {  AccountCreationGUI window = new AccountCreationGUI();  window.setVisible(true);  frame.dispose();                                }          });  btnRegister.setBounds(199, 170, 89, 23);  frame.getContentPane().add(btnRegister);  

AccountCreationGUI (I didnt add the other method to make this short)
