I use Gimp too although it is a bit involved. I have used LTspice too. Although I don't use a lot, Microsoft Visual Studio Community Edition is useful for programming. It is freely available (or was last I checked). I have one project in C++ with it. A point to note though is that it has the full environment and options so it can get a bit involved for novice programmers.
There are a number of other applications that I have but, thinking more in terms of what I use regularly, Coil 32 (now Coil64 is the latest with no future update of Coil32) for tuned circuit calculation and Notepad++ for basic code editing are very good. I use Windows and never really looked for other platforms.
