What is better to write a Windows application?

I'm afraid to run into glutaminase of antiderivative, but...
If the situation is that not everywhere even .NET installed (which means the max XP with SP early or even without them), the iron must be not very powerful. Why not try Delphi? As for me — better framework for developing Win32 applications that do not require .NET. The output will be native Windows application, which (subject to required skills) quickly developed and easily extended. In addition, the latest Delphi IDE (version 2007+) relative to suitable for a comfortable development.

MDA recalled:

\rXXX: If the computer was building, then asked to recommend a tool for hammering a nail, most people would advise to use a different model pizzini warehouse microscopes, pouring shit microscopes from other manufacturers, and only a couple of people silently held out the hammer.
\r
\rYYY: And from those two hammers, one would be a homemade mallet!
\r
\rXXX: Exactly. Anybody else would have said that all the LAMER, and instead of a nail you need to use a screw.
\r
\rYYY: AND would offer its own version of the screw with right-hand thread hex driver with Sun logo...
\r
\rXXX: AND then someone will come and say that they put everything in superglue and it seems worth it.
\r
\rYYY: AND someone to lament about what used to do without nails built and stood a century...

Settled on C# + winforms, though not had experience of coding (web only), figured out pretty quickly. In an Internet a heap of the documentation, the problems are resolved quickly, and more than half of the planned features can be implemented intuitively.

Yes, you have to get to install the framework, it's a minus. But in my case it is not particularly critical since I myself am a sysadmin, and need the computers he can install it.

Application for "state needs" and will require more documentation for the implementation, where you can specify the desired framework. So do not tushuytes :) to put it is the task of the system administrator, if the program needed, it it comes.

Or just c++ With Qt is IMHO quite a handy thing to develop...

if .net at least 2.0 is not worth it, it immediately should be put. Under windows + 2010 without dotNet has no meaning and no relevance.

What's wrong Python + PyQt/wx, Packed in one .exe? It is also possible to write math by taking the same PyPy and some Libu for mathematics (numpy is the same).
