One thing we learned from our IntelliGantt Rich Client and IntelliGantt Add In products is this-- there are a lot of people on the internet and they don't all speak English.
So we designed the IntelliGantt Web Part to be as easily localizable as possible, for all of our benefit. The result, we think, is a clean and simple UI that, in addition to being uncluttered with words, is very quick to localize. In fact, right now we only have 21 strings to translate in the UI. Since SharePoint column and view names come from SharePoint and are already localized, we just had to do a few things like 'Explore' and 'Search'.
If you would like to see the IntelliGantt Web Part localized for your language, here is the list of strings to translate. Either send your list of localized strings to support [at] teamdirection [dot] com or reply with your list in our forum. We will be happy to get your localized strings in as soon as we can to help you and your users.
