I'm not sure how well it works or how sophisticated / simple it is,
but the book "Microsoft SharePoint: Building Office 2003 Solutions
contains instructions for building a workflow engine  on page 351.
Also, in the book, the author mentions that his favorite 3rd party
workflow engine is K2.net at www.k2workflow.com.

In a related discussion with Microsoft last week, we asked why
Microsoft removed the workflow capabilities that were built into
their 2001 document libraries (still available via "backwards-
compatible" document libraries in 2003.) Most of what we were
looking for in simple workflow was in there, but we didn't want to
deploy something for which Microsoft support was waning. Here is
Microsoft's response, which confirmed that backwards compatible
libraries are probably not the right way to go:

1. The SQL based (NON backwards compatible document library)
workflow is a component/provided by Windows SharePoint Services.

2. Windows SharePoint Services is an evolution of SharePoint Team
Services. The support for Document workflow in WSS is MORE robust
than in STS. (via event handlers)

3. SPS workflow is the same in SPS 2003 and in SPS 2001 in
the "backwards compatible document library."

4. The Exchange based (Backwards compatible/version 2001) support is

5. There was not time in the WSS or SPS 2003 development timeframe
to develop  a "more robust" workflow to extend the WSS functionality
(SQL based). We elected instead to support event handlers so 3rd
parties could develop highly customized workflows to meet the
diverse needs of our customer base.

6. At this point, we do not know if the next version will contain
more workflow options or if we will continue to leave this to 3rd
party add ons. There are many different workflow designs out there,
and trying to build a product that can address all workflow
scenarios for all customers may be too large to encompass in the
SharePoint products.

Well it is true that K2net has a robust workflow for
sharepoint. Infact i have seen a demo early this
year..the price range for the engine  starts from 7000$
excluding per usage.

Since I don't have the book on SharePoint. Its not
availble on our market yet i am looking for a good
materials and understanding to build a small workflow
engine. I am totally blank  on that. Specially on
desiging the workflow..

So far microsoft is concern i guess they intentionally
didn't add workflow to let thrid parties get some

Yes u can do it with two different ways

By using Microsoft Infopath or by developing Web Part Pages in Share Point Portal

Infopath is used to develop  such kind of tasks but it has its own limitations. Developing a web part pages is easy and requires programming skills in asp.net and it less dependent if u r using share point portal. [Down load the soft ware development kit documentation for Share Point Portal from Microsoft web site
