No, there are two options: commercial (buy it) and open source community edition (which Fritzng uses) free, but only for personal use. The Get Qt now page should have two selections, commercial and community / open source, you want to choose the open source option. That said, selecting the options that you need to download can be complex and you need to do it in the correct order (which may be in the build instructions, I don’t remember) for instance you need to have Visual Studio installed before you install Qt so Qt will find the compilers.
There is a forum post “Build instructions for Linux and Windows” (in the developers section, referenced two posts back) if you click on that link it will take you to what documentation there is on building from source. There are fairly detailed instructions on what you need to do (although they are a couple of years and one Fritzing version out of date, there is also an update that I have not tried). Even with that it is not simple and assumes you are used to development tools.
There are many possibilities, and Kjell looked at (and rejected for various reasons) a lot of them before settling on the current scheme. He could spend all his time trying to find another solution, but both he and I would rather he spend that time on development of Fritzing. What I am saying (to everyone who is unhappy with the current scheme) is: if you don’t like the current setup then spend the time to fully document an acceptable alternative and propose it. Like it or not the, the current method is working and it is unlikely the developers will spend more time looking for an alternative. If you want one you need to do the work involved with making it happen (at some point you will likely need help from Kjell, as the official contact with Fritzing) but there is a lot of work to be done before that point, in the form of a business proposal of how your scheme will work and what it will cost in time and money.
Someone has to be willing to do that. I have done the instructions that exist while figuring out the build process from the (poor) documentation on the develpment wiki and documented it in the forum posting. I don’t do You Tube videos and am not likely to do much more on the build instructions as they should be clear enough if you have the necessary skill to do the build. It is complex, The code base is complex. It can not be made simpler to build from source. The alternative is to make a donation and download a packaged installation, but someone has to pay to create that packaged installation (and for the web site, forum and development.) We would be happy to hear of a practical alternative (that doesn’t involve stopping development to try some alternate funding scheme that may or may not work.
