How I got introduced to Qt and some basics?

Hello friends,
Today, I am going to talk about something very off-the-line and new, it's Qt. What is this? we will come to this later.

How I came to this? Actually, ... there is indirect link to, me reaching at Qt. I had XP on my laptop, and just 1 month before, I removed XP completely, and installed UBUNTU 8.04 in my suddenly awaken sense of open source sharing, pirated software crime etc. !!!

Things went very well, as I was doing my routine work, But I realized that, MS VC++, VB, is so strong for my application development, and I didn't know whether I can develop or learn my GUI, event based applications in Eclipse? (I still don't know!).
So, I was chatting once to my colleague Deepak on tea, we were chatting about why I wanted to switch to XP again? He suggested, use Qt yar, it is for C++ GUI development.
So, this way, I reached to Qt.

What is Qt anyway?

P.S.: credits for information available here is to : TROLLTECH
Following is the fundamental sequence of implementation events that happens in any GUI, or event-based application:
Step 1. Design your GUI according to your application's requirements;
Step 2. Add properties and variable names to the controls in your GUI;
Step 3. Add code to controls.
More to come ...

Cheers!
