WYSIWYG editor in texarea for Drupal configuration form

Question

Is it possible to use a WYSIWYG editor in texarea for Drupal site configuration form (system_settings_form).

This is how the configuration is coded now...

$form['my_module_text_bottom'] = array(
    '#type' => 'textarea',
    '#title' => t('Some text'),
    '#default_value' => variable_get('my_module_text_bottom', 'This is configurable text found in the module configuration.'),
    '#size' => 1024,
    '#maxlength' => 1024,
    '#description' => t("Some text."),
    '#required' => TRUE,
  );
  return system_settings_form($form);

Answer 1

The WYSIWYG or CKEditor modules should be able to do this.
