[Interest] find executable in Qt 4.8

I don't know about anything alike in Qt4, but reading the docs it seems 
quite straightforward and not too much work to implement that function 
Of course, it depends on how to detect "executables". By name, maybe 
trying out extensions (like ".exe", ".bat", ".cmd" on Windows) would be 
easy and fast (regarding performance). Parsing the file (or just 
checking the magic number) header might be some more work (and be 
somewhat slower) I guess.
Only thing requiring more effort, as I imagine, might be to 
differenciate many platforms or ones very different from the "common" 
ones (Windows, Linux, etc.).

kind regards
