Have a look here.
This is the form that is shown right now.

To add a new field you can actually use the same syntax as any blueprint field. Only that it is not written in yml but in php.

Example for a date field

<?php
$form = new Kirby\Panel\Form(array(
  'title' => array(
    'label'        => 'pages.add.title.label',
    'type'         => 'title',
    'placeholder'  => 'pages.add.title.placeholder',
    'autocomplete' => false,
    'autofocus'    => true,
    'required'     => true
  ),
  'uid' => array(
    'label'        => 'pages.add.url.label',
    'type'         => 'text',
    'icon'         => 'chain',
    'autocomplete' => false,
    'required'     => true,
  ),
  'date' => array(
    'label'    => 'Date',
    'type'     => 'date',
    'format'   => 'MM/DD/YY',
    'default'  => 'today',
    'required' => true,
  ),
  'template' => array(
    'label'    => 'pages.add.template.label',
    'type'     => 'select',
    'options'  => $options,
    'default'  => key($options),
    'required' => true,
    'readonly' => count($options) == 1 ? true : false,
    'icon'     => count($options) == 1 ? $page->blueprint()->pages()->template()->first()->icon() : 'chevron-down',
  )
));

The controller should look something like this.

$form = panel()->form(__DIR__ . DS . 'form.php', $parent, function($form) use($parent, $controller) {
  try {
    $form->validate();
    if(!$form->isValid()) {
      throw new Exception(l('pages.add.error.template'));
    }
    $data = $form->serialize();
    $page = $parent->children()->create($data['uid'], $data['template'], array(
      'title' => $data['title'],
      'date'  => $data['date'], // this is what changed
    ));
    $controller->notify(':)');
    $controller->redirect($page, 'edit');
  } catch(Exception $e) {
    $form->alert($e->getMessage());
  }
});

I only took the parts of the code here that are important for the functionality.
