Formgenerator?

Hi. I´m tired of buildung MySQL-input and update forms. Aren´t there any formgenarator supporting some further features like: -user events bevor and after the insert -data checking by RegExp and custom errorMsgs I tried PhAkt whicj is cool, but doesn´t support a fieldcheck or events after an insert. There is also ImpAkt which supports all the features but it´s nich OpenSource. thx
