Convert c++ windows.exe file to ios app

Hi, I am not sure where I should have posted this topic, but I have a simple calculating program made with c++, it uses enter key on keyboard a lot.

I would like to be able to execute in iPod touch. The support guy told me that you need to get AlwaysOnPC app to be able to use PC file, but he said it is Linux

operating system. So I installed Ubuntu Linux onto Virtual Box, I even installed Turbo C++ on it, but still I think it will be build a .exe file since I used Dosbox

emulator to install. Is there a way to make or change my original application to Linux application type so that I can upload it to AlwaysOnPc app in my iPod

touch??? Also I am not sure if I can use the same "Enter" key with iPod touch?

Another way is to make a Linux binary from .exe file, and to recompile and execute on iPhone or iPod touch, I am not sure how this can be done?

And another person suggested:

Try the following algorithm:
1) Install cygwin system on your Windows computer
2) Intsall gcc on your cygwin system with cross-compiler to linux systems
3) Compile your program under cygwin with gcc cross-compiler

and will have a linux application.

But I am not sure how to upload to iPod touch?

And I found also:

You'd need to convert to Obj-C, then build an app around that, then use it on iOS.

Can I do all of these in Windows 7 enviroment?

What do i have to have installed to make it work?

Any suggestions comments, or link, thanks.
