I too am new at this and I am all self taught when it comes to web design and it may not be the correct way to do it, however this is how I created a button and it worked for me.
On top of the menu click the "menu editor"
You need to create a page first so click on the "manage pages tab"
Create a page - give it a page name, title, summary and add your key words and click apply
Your new page will appear on the "existing pages" list. click on it and add your content you wish users to see.
On your original page (the one you wanted to have different menu buttons) there is a little hammer icon which is the "create a web form" click on this.
At the bottom left there is a "button" box - click on it and drop it in to the left hand "form" box.
At the bottom of the screen there is "input name" - put in here what you want the button to be called, this is for your reference only.
In the "value" box put the name of the box that your users will see. You will see the button name has changed from "Submit Query" to whatever you have called it.
When you click apply a box will ask you to enter a valid email address etc, click OK.
Tick the "use custom thankyou page" and scroll to the page you just created above.
Click Apply
You newly created button will appear on the page and you can move it to where you want it.
To test that it works, preview your website, and click on the button you created, as if you were a user.
You will then be taken to that page. If that does not work then let me know and I will explain how to create a hyperlink to the page you want. I just think creating a button is more professional.
I hope I haven't tested your intelligence with my step by step guide, apologies if I have.
