Добавление записи в базу данных через приложение javafx

1. Написал приложение, которое подгружает данные из моей базы данных (MySQL). При выборе строки ее можно удалить нажав на кнопку "удалить"

2. При нажатии на кнопку "добавить" открывается окно, в котором должны отображаться (textField) - названия колонок в базе. не знаю как реализовать это через код.

Предположим у меня есть таблица в базе - cinema с 3 колонками id_cinema, name_cinema, id_owner, также есть таблица owner с 2 колонками id_onwer и fio. При нажатии на кнопку "добавить" необходимо, чтобы открывалось окно добавления с подгружаемыми филдами для колонок и после нажатия на кнопку "добавить" - все введенные данные в филды добавлялись в соответствующую таблицу, которая была ранее выбрана в choiceBox.
