I'm used to working in a Delphi and C# environment which seem to have a rich set of third party components available. I'm currently wanting to do cross-platform programming in C++ using either qt or wxwidgets. Is there a large market for third party components? I was looking at sourceforge and that doesn't seem to show much that is useful (how the hell do you find out what components or features are in a project without downloading the source?). I'm thinking carousel/coverflow components, rich datagrids (like the sort DevExpress provide). Or is this, write your own territory?

There are a number of good quality third party Qt libraries, though I don't know of a centralized resource for finding them.
A few places to start looking:
http://www.ics.com/products/qt/addons
ICS provides the QicsTable, a high performance model-view-delegate table library, and resells various libraries by KDAB. (These are all available as a free download.)
http://www.qtcentre.org/contest-first-edition/finalists
QtCentre has an annual programming contest which awards interesting Qt-based tools and libraries. This year's contest is still being judged, but the finalists from last year can be seen at the above link. Check out the Custom Widget and Helper Library categories.

In addition to the ones by ICS and at QtCentre the Qt-apps website has some open source widgets/components for Qt.

For a crossplatform GUI development, Qt is the tool you should be looking for. I have used both. Here is what I feel about Qt
Building rich GUI is a piece of cake if you use Qt. It has a loads of GUI capabilities, starting with its Graphics View, OpenGL support, stylesheets that supports css. A mature painting system, Richtext formatting, Integration with Webkit, and I am sure I am missing a lot more here...
Qt has its own build system, qmake which creates platform dependent Makefiles, so no Makefile hassles. Moreover you get a single pro-file which is much easier to manage. For wxWidgets, you will need to create different Makefiles for the various compilers you intent to use.
Other advantages of using Qt over wxWidgets are - the Api is very easy to learn with its intuitive api, superb documentation and tons and tons of examples. This helps you get yourself productive pretty soon and thus getting your product early to marker. BTW Qt is a RAD tool. Moreover, there is a huge user base, and there are forums like QtCentre.org to help you with your questions. If you are planning to buy commercial license, you get support directly from Qt Software (trolltech).
You would obviously be using Qt's Model View pattern, allowing you to separate your business logic from the presentation tier. I would suggest that you write to "support at trolltech dot com" or "sales at trolltech dot com" to get more information. You can explain your requirements and they would be able to explain how Qt fits your needs.
You could also download the opensource version and have look at the demos. Coverflow: http://labs.trolltech.com/blogs/2007/11/02/pictureflow-on-windows-mobile/ , http://ariya.blogspot.com/2008/03/introducing-photoflow.html
As I said, if its Rich gui you are planning to develop, use Qt.

There is a third-party component for Qt - advanced data grid - Qtitan DataGrid. In it there are almost all necessary possibilities.
Ultra-fast processing of large data sets
Use of QStyle for rendering objects ensures that the grid blends into the UI design of any application
Two modes of vertical scrolling
Customizable colors of rows and columns
Two integrated table views
Column banding and grouping
Automatic width and height adjustment
Fixed columns
Flexible sorting
Column summaries
Integrated high-performance caching mechanism
Advanced paint engine for faster rendering of UI elements
Cross-platform support
API for external editors
