Help with Applescript dialog box

Hello,

I'm making a small application with Applescript, which gives the user a dialog box, and uses the selection made by the user.

I need to use 3 buttons for the choices, since there are 3 possibilities that this Applescript is made for. But, I do need an option to open up another dialog box.
Since Applescript Dialog boxes only allow for a maximum of 3 buttons, has anyone a suggestion on what to use.
I do not want to use a list, or user input with text.

Thank you.

 

Thanks Kryten and Mark for your info.

I checked Pashua out, but I think it's a bit complicated for a small AppleScript. As is using Xcode, even more

Thanks again for your reply, and I try to check both options out if I find the time.
