MacOS X : Choose app through answer dialog?

[David Egbert]

I'm building a helper application that needs the path to the main app.  I
thought this would be best facilitated by having the user choose the app by
using: 

answer file of type "APPL"

Unfortunately this doesn't work in X.

Is there another way I can get the user to select the path to the
application?

Thanks.
