I want to display multiple modules in a project with a text box and browse button for selecting the input files

Just create the control from a list.

// Just using a 'record' here to represent the data to be display
// Could also be a normal class
record Module(String check, String path)
{ }

...

   Composite body = .... // Parent composite from somewhere

   body.setLayout(new GridLayout(3, false));

   // An example list of modules
   List<Module> modules = List.of(new Module("Port", "Path 1"), new Module("PWM", "Path 2"), new Module("CAN", "Path 3"));

   modules.forEach(module -> {
      Button checkButton = new Button(body, SWT.CHECK);
      checkButton.setText(module.check());

      Text pathText = new Text(body, SWT.BORDER | SWT.READ_ONLY);
      pathText.setText(module.path());
      pathText.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false));

      Button browseButton = new Button(body, SWT.PUSH);
      browseButton.setText("Browse");
      browseButton.addSelectionListener(SelectionListener.widgetSelectedAdapter(event -> {
        // Example action to take when Browse is pressed
        System.out.println("Browse " + module.path());
      }));
    });

If you want to keep changing the list in the same dialog you can dispose the existing children and redo the Composite layout. The following method does that:

 void showModules(final Composite body, final List<Module> modules)
  {
    // Dispose any existing children
    Arrays.stream(body.getChildren()).forEach(Control::dispose);

    modules.forEach(module -> {
      Button checkButton = new Button(body, SWT.CHECK);
      checkButton.setText(module.check());

      Text pathText = new Text(body, SWT.BORDER | SWT.READ_ONLY);
      pathText.setText(module.path());
      pathText.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false));

      Button browseButton = new Button(body, SWT.PUSH);
      browseButton.setText("Browse");
      browseButton.addSelectionListener(SelectionListener.widgetSelectedAdapter(event -> {
        System.out.println("Browse " + module.path());
      }));
    });

    // Redo Composite layout
    body.layout(true, true);
  }
