 -   ## Phase IV: Adding a GUI Frontend
     The final phase of the project, Phase IV, creates a **graphical user interface (GUI)** to replace the console interface. The GUI is created using **Swing classes** to include **JFrames**, **JPanels**, and other GUI components. This GUI uses a combination of **BorderLayout**, **GridBagLayout**, and **FlowLayout** to manage the GUI's layout design.

 -   ## BankAcctAppGUI Class
     The **BankAcctAppGUI class** is responsible for implementing the **graphical user interface (GUI)** introduced in **Phase IV**. It utilizes **Java's Swing library**, incorporating **JFrame** for the main application window and **JPanel** for creating distinct sections within the interface. **FlowLayout**, **BorderLayout**, and **GridBagLayout** are implemented to position GUI components in an intuitive manner. The GUI leverages the **enhanced data validation engine** from the **DataEntry class** to ensure data integrity and security. This class facilitates user interaction with the application through a more visually appealing and user-friendly interface. More details and screenshots are provided in the [Functionality & Rationale](#functionality--rationale) and [Running Application Screenshots & Demo](#running-application-screenshots--demo) sections below.
