my requirement
I select a point on the map and some
pop up or some thing has to come up asking for what have to be
displayed
Ex. roads, buildings, homes, etc
user can select one or more
A couple of examples for you - the select tool will make a small box (the size of 3x3 pixels) if you click once and use that to set the selection for the current layer.
There is an example tool (in code examples) that will go through each layer in the map (in visual order) trying to return the first selected thing (or maybe it makes a list?)
The get Info tool does almost exactly what you want; it opens a view; and lists all the things that were clicked on in a list; and as you click on them you can see a summary of them (for a WMS layer it uses getInfo, for a feature layer it shows the feature definition). It is not a pop up but it shows you what to do ...
Now do you mean a "pop up"
- like a toolbar? Look in the eclipse docs for "infopop" and friends; they have support for popups in the framework; and then do what the info tool does and just choose to show your result differently
- like a dialog? Make a dialog similar to the InfoView ...
Cheers,

after selecting by the user that the
map has to display the information associated with that point
I know how to create custom tool to

Is there some thing like pop ups
available on uDig probably the selection will be with check boxes
