Let me make some assumption about what you actually did.
1) You started with VW 7.4
2) You loaded the SeasideForWebToolkit parcel into the image using the 
parcel manager;
the Seaside parcels on the VW distribution are for version 2.5b8
3) Thereafter you loaded the SeasideForWebToolkit bundle (version 
2.6a2.115.0 ?)
from the public repository

This is creating a mess (although it may work somehow). Instead, you 
should unload all
the Seaside parcels prior to loading from the public repository or even 
better, you should
rebuild a Seaside 2.6 image starting from a virgin image. In case you 
want to try the unload
method, the parcels to unload are SeasideBase, SeasideForWebToolkit and 
SqueakBase.

You did not say what symptoms are produced by your code.
However, I can quickly spot a few errors.
a) You need quotes around 'Enter password'.
b) You need quotes around 'Login!'
c) You should use #break rather than #br.

Also you may want to combine
       html attributes value: 'Login!'.
       html submitButton.
as
       html submitButtonWithText: 'Login!'.

I do not have a sample form usage, but the Canvas version of your code 
would look like this

   (html form)
       defaultAction: [self confirmLogin];
       with:
            [(html heading)
                level3;
                with: 'Welcome to my site'.
            html bold: 'Enter login name:'.
            (html textInput)
                withValue: '';
                callback: [:v | self login: v].
            html
                break;
                break;
                space: 3;
                bold: 'Enter password:'.
            (html passwordInput)
                callback: [:c | self password: ((MD5 hash: c) 
asHexString asLowercase) ].
            html paragraph.
            (html submitButton)
                text: 'Login!'].
