Using Menu Buttons as Link Buttons

Hi,

I am not sure this is in the right place, but I hope it is.

I have a website:

And I was wondering is there any way to use the Buttons on the menu as just regular buttons?

For instance, I have a download page…it has buttons on it(You must be logged in to view that page)and there nice, but they don’t fit as well as the buttons on the menu.

Is there a way to out a menu button on a post or page and customize what the text on it says and where it links to?
