Add a button on a figure and to close the figure in MATLAB

Question

I have a set of data that i have pulled out of the database. I have displayed them in a figure window, but i would like to have a button in which where it closes the figure window or does some other function to it.

This is the code that i have so far :

f = figure('Position',[200 200 250 500]); % size of the figure object
dat = listofPdb.Data;
set(f,'name','List of PDBs available','numbertitle','off') %renames the Title Figure
cnames = {'PDB-Codes'};
rnames = {};
t = uitable('Parent',f,'Data',dat,'ColumnName',cnames,... 
            'RowName',rnames,'Position',[100 100 95 350]);

Please advise.
