Making a program with forms and saving them

I want to create a program with forms like a web page form (talking about style not html). On each of my forms I want to be able to put a save button on them that when pressed it will save all the infomation in the what was once blank form as default so when the form is accessed again all the information is there.

The save button will also have to have a backup method where I can save the form information and the form itself in some folder. Each time save is pressed it should save into that folder with the file named as the current date and time.

Also, when it saves, as a backup into that folder is it possible to change the attributes of the form so that it cannot be edited anymore?

Is that possible and is it fairly easy? Once I know the language of course.

Also, can I put C++ code into an html page to have it do the same thing except saving as an html page and not my progam ext.

It is possible and not too hard once you know the language and the WinAPI. At least I think so, I don't get what you want to do exactly.

You can't put C++ code in a web page.

What about C#? Can I put that in a web form?

I think so, but not sure. Not in a cross-browser compatible manner anyway.

The language to put into web forms is JavaScript, but you can't use that to save or load anything.

Just thought I would ask. Thank you.
