Summer: I think these two code snippets should answer all your questions:
% First for a regular figure window.
s = uint8(randi(255, [512,512]));
hFig = figure
imshow(s,[]);
title('Title Test', 'FontSize', 15);
% Give a name to the title bar.
set(gcf, 'Name', 'Demo by ImageAnalyst', 'NumberTitle', 'Off')
% Now for the imtool window.
hToolFig = imtool(s);
set(hToolFig, 'Name', 'This is S in the imtool window');
% Note: close all won't close imtool windows.
% imtool close all; % Close all imtool figures if you have the Image Processing Toolbox.

hFigure = imtool(I,[]);
then hFigure is a handle to the figure created by the Image Viewer. If that is the case, then you might be able to manipulate the name of the figure as
set(hFigure,'NumberTitle','off','Name','show some description');

Summer - for title, you can pass the handle of the axes that you want the title to appear over. I don't have the Image Processing Toolbox, so I'm guessing that you could do something like the following
hFig = figure;
imshow(s);
title(findobj('Parent',hFig,'Type','axes'),'title test');
So we use the findobj function to find the object whose parent is hFig and is of type axes. Here we assume that there is only one axes on the figure.
The above may be overkill, since you could probably just replace it with
title(gca,'title test')
where gca gets the current axes handle. But you seem to be suggesting that that won't work (given your question and code). Note that there was no image in your comment.
