Help with translating java script code into ASM code

Hi,
I am a total newbie, although I have a little programming knowledge Rolling Eyes

Here is what I need to do, but I am not skilled enough so I can not manage to do this without help...
I need to write a small windows GUI generating random numbers.
To be more specific:
To the constant values, for example "999", "321" and 743, I need to add 2- digit RANDOM numbers...
My java script code looks like this:

Code:

function getRandomNumber(max)
      {
        return Math.round(Math.random() * max);
      }

      function generateKey()
      {
        prefix = ["999", "321"];
        suffix = ["1", "2", "3", "5", "6", "7", "8", "9", "0"]

        return prefix[getRandomNumber(prefix.length - 1)] + getRandomNumber(9) + suffix[getRandomNumber(suffix.length - 1)];

My question is how the above code can be represented in asm code ... Rolling Eyes

well I started to write the skeleton of this program, but I do not have any clu how to write it correct and complete..

Code:

format PE GUI 4.0
entry start

include '%fasminc%\win32a.inc'


ID_GENERATE     = 102
ID_PAPAR        = 103

section '.code' code readable executable

  start:

        invoke  GetModuleHandle,0
        invoke  DialogBoxParam,eax,37,HWND_DESKTOP,DialogProc,0
  exit:
        invoke  ExitProcess,0

proc DialogProc,hwnddlg,msg,wparam,lparam
        push    ebx esi edi
        cmp     [msg],WM_INITDIALOG
        je      wminitdialog
        cmp     [msg],WM_COMMAND
        je      wmcommand
        cmp     [msg],WM_CLOSE
        je      wmclose
        xor     eax,eax
        jmp     finish

Any help will be appreaciated and I thank you all in advance!
