TinyMCE plugin

Hello, I am in need of a plugin for TinyMCE v4 that will allow users to create form fields. It would need to be very similar to the process of creating links, in that you can: 1) write out page content 2) select a portion of the text or click to place the cursor where you want the input placed. 3) press the new "insert form element" button from the toolbar 4) a dialog box pops up, asking for the label, input type (text, textarea, email, select, etc), field name (default to label), placeholder text, a textbox to list options (if is select or as a datalist) 5) on pressing the save button, it inserts the input element. and if you click on the element and press the "insert form element" button, it allows you to edit the details. It would be great if I could set the html to wrap the form fields in as my CSS requires that input elements be wrapped in a fieldset block and setting the label as an attribute. If I could specify this in the TinyMCE init settings, that would be great!
