mysql – is there a plugin? – design a custom form to insert it into a custom table

I just started using WordPress a few weeks ago and I do not know any php. I need to design a custom form (example fields: Name, Age, DOB) in a custom table in mySQL (mytable.name, mytable.age, mytable.DOB).

With wpdatatables There is a CRUD way to do this, except that the presentation is through a table, not a form with text entry fields. In my research, there are many forms to create custom forms, but they all write to a default table created by an add-on or do not write to the database.

Is there anything that allows for further customization (that is, it allows me to use a SQL statement for more or less) INSERT myform.name.data, myform.age.data, myform.DOB.data IN mytable.name, mytable.age etcetera etcetera.)?

Thank you!
