Just a little extension to the Windows Mobile file explorer. When you tap’n’hold on a EXE file then you can add it as shortcut into Start Menu. The tool should work with any version of Windows Mobile and on any resolution, if you use WM6.5 then the dialog will also appear in finger friendly style!
In the explorer context menu will be a new entry “Add to start menu”. Tap it and a window will appear and asks you to select the folder in start menu into which you want to add the app.
