Open file in folder with command line program

Question

I have a file, which is in native format for a given program [1] I have installed. This program I can start from Terminal.app and within the program I can open the file. The question is if I can have associated with this specific filetype this program and when I double click on a file of this type I can have a Terminal.app opened with my program running inside opening the file for me.
Btw, on a regular Linux/Unix I would just associate this filetype with the path to my program. On Mac I can associate only with .app.. Is there other way?

I do not fully understand your question.
You need to make your program into an application. I have not programmed on Mac OS so I to not know the details. You could hack some existing app. I do know that the plist file for an app points to the starting program.
Another work around would be to write an apple script file to call your program.
This applescript invokes a unix program.
   Run in the Script Editor.
   Click on the Event Log tab to see the output from the log statement
   Click on Run
   For running shell commands see:
   http://developer.apple.com/mac/library/technotes/tn2002/tn2065.html
on run
   -- Write a message into the event log.
   log "  --- Starting on " & ((current date) as string) & " --- "
   -- ask the user for the folder name.
   -- quoted form of (POSIX path of (choose folder))
   set theFolder to "/Applications/Utilities/Disk Utility.app"
   set theFolder to quoted form of theFolder
   log "quoted form is " & theFolder
   -- running two Unix commands. Separate with a semicolon 
   set fromUnix to do shell script "cd " & theFolder & "; ls -ld ."
   log fromUnix
   display dialog fromUnix giving up after 30
end run
This applescript program received a file dropped on it.
There is a lot of extra stuff but look at on open dropped_items This line gets a list of files dropped on the applescript. Your have to change the name format.
on open dropped_items
   -- Remember you need to turn on enable assistive devices
   -- this lets applications software to access screen elements
   -- blue apple > system perferences > universal access > enable assistive devices
   -- Write a message into the event log.
   log "  --- Starting on " & ((current date) as string) & " --- "
   -- set see to alias "Macintosh-HD:Users:mac:Desktop:app.html"
   -- set dropped_items to {see}
   set the_app to "Safari"
   repeat with dropped_item_ref in dropped_items
      --set UrlBase to "xzzx FILE://" & POSIX path of dropped_item_ref
      --display dialog UrlBase
      -- Activate
      activate application the_app
      -- Open the URL 
      tell application the_app
         open dropped_item_ref
         -- print dropped_item_ref
         tell application "System Events"
            tell process the_app
               delay 3
               -- click menu item "Print..." of menu "File" of menu bar 1
               keystroke "p" using command down
               delay 1
               keystroke return
               delay 10
               keystroke "w" using command down
            end tell
         end tell
         --quit
      end tell
   end repeat
end open
