Wine and Ubuntu are free software. You can use for anything. If you package with a commercial product you must quote the GNU license. Windows DLL's etc. (included with windows) and often needed to make windows software run on wine are not free software and cannot be copied. Best not to use wine.

2. Is it legal to produce commercial product on window based evaluation software.

Probably not. Check the EULA of the evaluation software.

Like software A has evaluation period for 30 days & meantime app is developed & then can be sold commercially.

Probably not. As above.

 

Hello,

There is no problem at all to use wine ( http://www.winehq.org/ ) on any linux system.
A lot of windows programs will work, but not all, it has still some way to go.

Of course you can use wine to look at trial versions of windows software.
Always obey the EULA (End User Licence Agreement).

Better is to look for a comparable open source software. (my own opinion).

I do not use windows at home, but have suse linux ( http://www.opensuse.org/en/ ).
In there you can get extra repositories with a heap of software.
The electronics software can be found in the scientific repository.
