There is currently no manual for the form designer.
The ISPConfig form designer is mostly for writing dabase driven forms to store information in the database. I think it is not suitable for an installer. Maybe you shall have a look on the ispconfig update installer. You may extend it to support installations to website directories so even custom installations of the phpmyadmin and webmail package might be possible.
A short documentation on the installer file format can be found here.
