How can I create forms that send email in wordpress?

I'm new to PHP and WordPress. I've been searching for this since an hour and I've found some solutions but they either do not fit or I couldn't set them up.

I have a contact form and another form which has values changed with javascript as user clicks to some buttons. So I don't know how to integrate Contact Form 7 to this.

I tried wp_mail() and it didn't work.

I am using XAMPP localhost, is that the reason why they do not work?

When I fill the form and click submit, same page reloads but either page cannot be found (same link just query strings added) or page is blank white.

How can I successfuly send emails containing form information in WordPress?
