Learning python syntax in 2 weeks is easily achievable if you go through 
the official tutorial at python.org. It is designed for people coming from 
another language, especially C++ or Java. If you work through it at a 
sensible pace - ie slow enough to think about it - you should be done
in 2 or 3 days. From there you will know enough to start working through 
the Django tutorial material and write short simple Python function and 
programs.

As others have said, trying to convert your knowledge of C++ into 
Python is likely to result in you writing Python that looks like C++. 
It is also likely to introduce bad habits based on C++ limitations.
You need to learn the Python way of doing things (and its limitations!)

Most Python IDEs do at least basic tooltips and such but if you are 
familiar with Eclipse then you can install PyDev and get all the usual 
Eclipse tools, including a good debugger. The one thing that is less 
useful in Eclipse is its interpreter prompt, but you can just use a tool 
like IDLE or Pythonwin or IPython in a terminal for that.

Python supports all the different styles of web development but Django, 
like most modern web tools separates code from presentation.

Since it is all built on CGI it is always a good idea to understand 
what is really going on. But raw CGI skill is not essential to get started 
in Django.

Django is a framework for rapid Web development but it is very 
different to, for example Glade. It is not an IDE or visual editor.

If its a web server based app then installing Python and Django 
on the server and loading your packages on is a better bet that 
trying to create an exe file os similar.

Yes, but it will be a steep curve.
Ask lots of questions, and read lots of documentation.
Ask the questions in the place most likely to answer them 
correctly! (ie python stuff here, Django stuff on a Django list)

I've been programming for about 30 years and have learned 
well over 20-30 languages. C++ was the hardest to learn and 
took about a month to get comfortable, most take a week.
Becoming an expert, now that's a different thing altogether - it took 
me about 4 years to reach that in C++ and about 1 year to lose 
it again! I'm still learning in Python after 10+ years! (Mainly 
because I don't use it for industrial stength projects)
